Preparation of Aliquat 336-impregnated porous membrane

Asai, Shiho; Watanabe, Kazuo; Saito, Kyoichi*; Sugo, Takanobu*

Aliquat 336, tri-${it n}$-octylmethylammonium chloride, was impregnated into the polymer chain grafted onto a porous 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 per kg of the GMA-grafted porous 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 dissolved in 1 M hydrochloric acid was forced to permeate through the pores of the Aliquat 336-impregnated porous membrane. The binding efficiency was found to be 69%.
