摘　　要：本文研究季胺N_(263)和叔胺N_(235)两种浸渍硅球对钯的吸附机理,在本实验条件下通过阴离子交换反应,N_(263)的吸附过程是:N_(235)的吸附过程为:Under the different conditions,the adsorption of palladium with quaterary ammonium salt(N236)-silica and tertiary amine(N235)-silica as stationary phases is studied. The experimental result indicates that the adsorption mechanism of Pd( Ⅰ )is similar with liquid-liquid extraction in the different acidity range. The main product of trialkyl-methy 1 ammonium chlorode is R3CH3 N. HPdCl4 and that of trialkyl amine is(R3NH)2 · PdCl4 by anionic exchange reaction.
