POLY(4-VINYLBENZYL)TRIMETHYLAMMONIUM CHLORIDE) RESIN WITH REMOVAL PROPERTIES FOR VANADIUM(V) AND MOLYBDENUM(VI). A THERMODYNAMIC AND KINETIC STUDY

ABSTRACT Ion exchange resin poly(4-vinylbenzyl) trimethylammonium chloride(P(ClVBTA)) was synthesized and its removal properties toward vanadium(V) and molybdenum(VI) were evaluated and compared with those of the Amberlite IRA-402 commercial resin. The resin was characterized by FT-IR spectroscopy,...
