    Abstract: We developed a method of modifying the polyester material to produce ion exchange fiber sorbents. The production of cation exchange sorbents involved the treatment of polyester fibers with a 20–25% solution of NH2NH2H2O at 70–90°C and a 5% solution of NaOH at 40°C. Anion exchange sorbents were prepared by the treatment of cation exchange sorbents w... Show More
