At the current, 65 percent of the total volume of ionites produced worldwide is used for obtaining purified and desalinated water used in thermal and nuclear power plants, chemical production of hundreds of forms, radio engineering and electrical engineering industry, machinery and utility industry, and for water purification. The use of complex-forming sorbents containing sulfur and phosphorus in various industries is important for the implementation of production processes based on modern waste-free technologies. In the world, scientific-research works directed at the synthesis of...

Sorbents are widely used in hydrometallurgy to concentrate various metal ions and neutralize waste solutions containing heavy metal ions. A wide range of ion exchange, complex polymers, and polymer matrices have now been developed. It is known that the industrial methods of obtaining such sorbents are polycondensation, polymerization, and copolymerization of monomers with different functional groups. Chelating polymer sorbents are widely used to concentrate and separate trace amounts of elements. The future development of their use is related to their high selectivity and effective effect in...
