Preparation of Aliquat 336-impregnated porous membrane
چکیده انگلیسی

Aliquat 336, tri-n-octylmethylammonium chloride, was impregnated into the polymer chain grafted onto a porous hollow-fiber membrane. 6-Aminohexanoic acid and octadecylamine were introduced into the epoxy group of the graft chain. The amount of impregnated Aliquat 336 was 1.2 mol/kg of the GMA-grafted porous hollow-fiber membrane. The coexistence of 6-aminohexanoic acid and octadecylamino groups enabled the high-density and stable impregnation of Aliquat 336 to the graft chain. Palladium chloride (100 mg-Pd/L) dissolved in 1 M hydrochloric acid was forced to permeate through the pores of the Aliquat 336-impregnated porous hollow-fiber membrane. The binding efficiency, defined as the ratio of number of moles of palladium adsorbed to half the number of moles of impregnated Aliquat 336, was found to be 69%.
