Extraction of uranium(VI) with binary mixture of LIX 984 and naphthenic acid

Extraction studies of uranium(VI) with LIX 984 (HX) (an equivolume mixture of LIX 84 and LIX 860 in kerosene having a resulting mixture of 5-dodecyl salicylaldoxime and 3-nonyl acetophenone oxime in kerosene) and its binary mixture with naphthenic acid (HR) ( a mixture of cyclic aliphatic carboxylic acids) have been made. The proposed extracted species are found to be UO2X2(HR)2n/UO2R2(HX)n/UO2R2X(HR)2n(HX)n on the basis of slope analysis for individual LIX 984 and its binary mixture, respectively. Effect of various diluents on the extraction with individual extractants and their mixture was studied. Influence of addition of various salts on the extraction has also been carried out.
