Abstract

Aliquat 336 was impregnated onto the polymer chain grafted onto a 2.0-mm-thick porous sheet with a porosity of 75% and a pore size of 1.2 μm via the graft polymerization of glycidyl methacrylate and the subsequent reaction of the epoxy group with mercaptoundecanoic acid. In a 2:1 ethanol/4M NaOH (v/v) mixture, Aliquat 336 was impregnated at a density of 0.85 mmol/g, which was comparable to that of conventional Aliquat-336-impregnated polymeric beads. The dynamic binding capacity for palladium was 0.60 mmol/g when 100 mg-Pd/L palladium chloride solution was forced to permeate at a space velocity of 3700 h-1..
