The Institute of Chemical Sciences is one of the largest research institutes in Kazakhstan. It consists of 8 laboratories. The Institute employs 2 academicians, 2 corresponding members of the National Academy of Sciences of the Republic of Kazakhstan, 23 doctors and over 25 candidates of science, as well as 9 PhD doctors.
Laboratory of Ion Exchange Resins and Membranes
The laboratory was organized by the Decree of the Bureau of the Presidium of the Academy of Sciences of the Kazakh SSR No. 60 dated July 27, 1960 as part of the Department of Chemistry of High-molecular compounds of the Institute, headed by Academician of the Academy of Sciences of the Kazakh SSR S.R. Rafikov.
From 1968 to 2020, the permanent head of the laboratory was Academician of the National Academy of Sciences of the Republic of Kazakhstan, Honored Scientist, laureate of the State Prize of the Republic of Kazakhstan in the field of science and technology, Doctor of Chemical Sciences, Professor E.E. Ergozhin. In 1974, at the age of 33, he successfully defended his doctoral dissertation on the topic "Synthesis and study of the laws of formation of new ion-exchange and redox polymers" and was included in the collection of the publishing house "Young Guard" of the Eureka series "Daring Youth", Moscow, 1978, telling about young doctors of sciences of the USSR who defended their doctoral dissertations at the age of 35.
Currently, the head of the laboratory is a student of Academician of the NAS RK E.E. Ergozhin, Doctor of Chemical Sciences, Professor T.K. Chalov.
Scientific direction: synthesis, study of physico-chemical characteristics of mesh ion-exchange, complex-forming and redox polymers; creation of original methods for regulating and controlling their permeability and selectivity with respect to complex metal ions and organic compounds; development of methods for obtaining new ion-exchange membranes with increased physico-mechanical and electrochemical characteristics and the creation of electrodialysis desalination plants based on new generations.
The Laboratory of Ion Exchange Resins and Membranes is working with three oil refineries to treat industrial wastewater to provide recycled water supply.
At “Petrokazakhstanoyl Products” LLP, the effectiveness of using a fine cleaning unit at the 3100 plant (chemical water treatment) was investigated. The experience of designing and operating fine filters, both based on cartridge elements and bag elements, makes it possible to assume that the use of bag elements is several times more effective. Filter bags are made of polypropylene (for cold water) and polyester (for cold and hot water) and can be used repeatedly. With repeated regeneration of the bag filter, its performance is reduced by no more than 5%.
Based on the scientific developments of the A.B. Bekturov Research Institute, the effectiveness of the use of a fine cleaning unit consisting of bag filters and 3 stages of purification before reverse osmosis installation was investigated in factory conditions on the territory of “Atyrau Oil Refinery” LLP. Long-term tests were carried out by launching the pilot plant in the operating mode on the territory of ANPZ LLP.
Long-term tests were carried out to reduce the hardness and iron content in steam condensate during reverse osmotic cleaning of the territory of “Pavlodar Petrochemical Plant” LLP. The data obtained show that the pilot reverse osmotic installation designed at the A.B. Bekturov Research Institute has shown its high efficiency.
A technological solution has also been developed to clean the mine waters of the Don Mining and Processing Plant of JSC “TNK Kazchrome” from pollutants. The initial characteristics of the mine water under study have been studied. The analysis was carried out and the optimal technological solution for the effective purification of mine waters from chromium (VI) ions was selected. It has been established that the ion exchange method is the most effective, followed by electrocoagulation, and the reagent method closes this series. Laboratory studies on the sorption of chromium (VI) ions by new anionites synthesized in the laboratory were carried out on a laboratory test bench. A basic technological scheme of water purification from chromium (VI) ions has been developed, which consists of modular blocks of reagent-mechanical, sorption, membrane, ion exchange and bacterial purification.
Currently, research is underway to develop a technology for water purification of the tailing dumps of “KAZZINC”| LLP to reduce environmental pollution by wastewater. Further, long-term tests will be carried out on a manufactured experimental stand with different modes and a comparative assessment of the effectiveness of the proposed methods and options for their joint application will be carried out.
The head of the laboratory is Doctor of Chemical Sciences, Professor Chalov Tulegen Kamenovich.

Laboratory of Polymer Synthesis and Physicochemistry
Scientific direction: the research of the Laboratory of Synthesis and Physicochemistry of Polymers is aimed at developing new macromolecular structures with specified properties. Scientific research is carried out by 2 research groups: 1st group led by the Head of the laboratory, Doctor of Chemical Sciences, Prof. Jumadilov Talkybek Kozhataevich and 2nd group led by the chief researcher, Doctor of Chemical Sciences, Prof. Umerzakova Maira Berdigalievna.
The research group of Prof. Jumadilov is engaged in the development of innovative methods for the extraction and separation of target metal ions based on the remote interaction of rare-crosslinked polymers and hydrogels. Depending on the nature of the target metal ions, new methods are being developed for both parallel and sequential extraction from product solutions of hydrometallurgy.
The research group of Prof. Umerzakova is engaged in the development of new polymer composite materials based on (co)polyimides, including alicyclic and aromatic links, and various organic, inorganic synthetic and natural compounds with improved performance characteristics. Depending on the nature of the additive used, they can be used for the production of colored heat-resistant fibers, in microelectronics, electrical engineering, mechanical engineering and many other fields of science and technology.
Laboratory staff carry out research work on the Project AP08856668 "Development of fundamentally new methods for the extraction of rare earth metal ions of the cerium group based on the effect of remote interaction of functional polymers and molecular imprinting" (supervisor - Head of the laboratory, Doctor of Chemical Sciences, Prof. Jumadilov) within the framework of a Competition for grant funding for scientific and (or) scientific and technical projects for 2020-2022 (MES of RK).
During the period of the project implementation, the following results were obtained: functional rare-crosslinked polymer hydrogels of polyacrylic acid (hPAA), polymethacrylic acid (hPMAA), poly-4-vinylpyridine (hP4VP), poly-2-methyl-5-vinylpyridine (hP2M5VP) were synthesized. It has been established that rare-crosslinked polymer hydrogels PAA, PMAA, P4VP, P2M5VP undergo ionization in an aqueous medium. As a result, there is an increase in the values of specific electrical conductivity, a change in pH and the degree of swelling throughout the entire time of interaction of polymers with the aqueous medium. The nature of the pH change directly depends on the nature of hydrogels. In the presence of hPAA and hPMAA, its decrease occurs due to the release of hydrogen ions during the ionization of macromolecules (dissociation of carboxyl groups occurs). In the presence of hP4VP and hP2M5VP, the pH increases as a result of the association of protons formed during the dissociation of water molecules by pyridine ring heteroatoms. Based on the synthesized hydrogels PAA, PMAA, P4VP, P2M5VP, the intergel systems hPAA-hP4VP, hPMAA-hP4VP, hPAA-hP2M5VP, hPMAA-hP2M5VP were developed. The remote interaction of the above-mentioned rare-crosslinked polymer hydrogels leads to significant changes in their electrochemical and conformational properties. At the same time, areas of maximum ionization of the initial rare-crosslinked polyacids and polybases appear. It was found that with an increase in the proportion of the second component in the intergel pairs, a significant increase in the degree of swelling of the first polymer occurs. Synthesized polymers with molecular imprints have been synthesized. Cerium, praseodymium, neodymium, samarium, and europium nitrates were chosen as templates. Methacrylic acid (MAA) and 4-vinylpyridine (4VP) were chosen as functional monomers, ethylene glycol dimethacrylate (EGDMA) and diethylene glycol dimethacrylate (DEGDMA) were used as the initiator, azobisisobutyronitrile (AIBN) was used as a stabilizer, hydroxyethyl cellulose (HEC) was used, toluene was chosen as a pore-forming agent. Deionized water was used as a polymerization medium. Polymers with molecular imprints (MIP) have high mechanical strength due to a high degree of crosslinking, while they are weakly subjected to swelling, ionization. Lower values of the specific electrical conductivity, pH and degree of swelling of the MIP structures with a template when compared with the control sample indicate the presence of cavities complementary to the template (rare earth metal ion) used in their synthesis.
For 47 years of scientific activity, Prof. Jumadilov has made a huge contribution to the development and formation of such scientific directions as physical chemistry of aqueous and non-aqueous solutions of ionic and nonionic linear and crosslinked polymers based on vinyl monomers; electrochemistry, study of conformation and complexation of hydrophilic polymers and copolymers based on vinylpyridines, vinylimidazoles, alkylacrylates and acrylic, methacrylic acids; molecular complexes of polymers; patterns of formation of ion-conducting complexes and composites in non-aqueous media; intergel- and interpolymer systems; activation phenomena during remote interaction of acidic and basic polyelectrolytes; high sorption activity of activated ionogenic polymers; selective interpolymer systems; methods and technologies for concentrating and extracting transition and rare earth metal ions from aqueous systems. Recent developments have been devoted to the study of electrochemical, volume-gravimetric and sorption properties of hydrogels and ion-exchange resins, as well as interpolymer systems based on them.
Currently, the laboratory staff is conducting research work on the Project AP14870002 "Development of modern methods for separation and extraction of rare-earth metals from concentrates and technological solutions of sulfuric acid leaching" (scientific supervisor - Head of the laboratory, Doctor of Chemical Sciences, Prof. Jumadilov Talkybek Kozhataevich) within the framework of a Competition for grant funding for scientific and (or) scientific andtechnical projects for 2022-2024 (MSHEof RK).
