Abstract

1-(2-hydroxyl-5-nonyphenyl)ethanone oxime (LIX84-I) was impregnated into polymeric particles with interconnected spherical pores by the solvent evaporation method. Divinylbenzene was used as a wall material and polymerized in the organic phase of a (W/O/W) emulsion by free radical polymerization. The diameter of the polymeric particles was almost constant at around 208±26μm. The impregnated yield of LIX84-I in the polymeric particles was higher than 80% in all preparation conditions. The extraction of Ni(II) with the polymeric particles impregnated with LIX84-I sharply increased at pH values higher than 6. It is confirmed that three molecules of LIX84-I reacted with one Ni(II) ion by quantitative analysis of the relationship between the maximum amounts of Ni(II) extracted and the amount of LIX84-I impregnated in the polymeric particles. The extraction rate of Ni(II) was effectively accelerated by the presence of the interconnected-spherical pores in the inside of the polymeric particles.
