Abstract: This work describes the preparation of functional polymers containing 2-mercapto-1methylimidazole and guanylthiourea ligands from chemically modified vinylbenzyl chloride/divinylbenzene copolymer (VBC/DVB). The resins were used for the removal of Ag(I) from synthetic and real chloride solutions.… read more here.
