Annotation. Since the last century the fiber sorbents are known to have excellent kinetic characteristics due to their physic–chemical structure. Their major advantages include a large specific surface, a high swelling capacity, a good mechanical strength and convenient use. Therefore the development of new types of ion exchange fibers is attracting attention from many laboratories all over the world. In the present study novel cation and anion exchange fibers for the removal of metal ions from wastewater have been developed. The effective removal of Co(II), Ni(II), Cu(II), Zn(II), Sr(II), Cd(II), Sb(II), Cs(I), Cr(VI) ions and molecules labeled by radionuclides from model or waste water by the newly developed fibrous sorbents has been achieved. The adsorption properties of the cation and anion exchange fibers have been shown to depend on the pH value.
Keywords: Polyester, Cation Exchange, Anion Exchange, Fiber Sorbent, Wastewater Treatment.
