sulfate solution; saponified bi(2-ethylhexyl) phosphoric acid (D2EHPA); zinc; solvent extraction zinc extraction reagents and relatively low prices of zinc metal, the applications of solvent extraction of zinc from sulfate solution are limited [8-9]. Organic......
. Namely, the extraction rates of copper and cadmium were 99.8% and 1.54%, respectively. The copper-loaded organic phase was stripped for one time with 200 g/L sulphuric acid. The stripping rate... in this solution through solvent extraction by using kerosene diluted LIX984N as extractant. Therefore, it is favorable to recover cadmium ion from the zinc ammonia/ammonium sulphate solution......

organic / aqueous (O/A) phase ratios (Fig. 7). Fig. 7 Effect of O/A ratio on zinc extraction At a phase ratio of 1:1, about 99% zinc was extracted from the aqueous phase, but about 23% of cadmium was co...:1 and pH 6. The removal rates of Fe, Pb and Cu from the solution were greater than 98.9%, and As removal rate was 99.6%. A solvent extraction with P204 was used for the separation of zinc and cadmium......

Removing cadmium from electroplating wastewater by waste saccharomyces cerevisiae DAI Shu-juan(代淑娟)1, 2, WEI De-zhou(魏德洲)1, ZHOU Dong-qin(周东琴)1, JIA Chun-yun(贾春云)1, WANG Yu-juan(王玉娟)1, LIU...; Abstract: The appropriate condition and scheme of removing cadmium from electroplating wastewater were investigated by adsorption-precipitation......
the biosorption data. The uptake of cadmium was higher in weak acid condition than in strong acid condition. Nearly no sorption of cadmium occurred when the pH value was lower than 2.0. Biosorption... fungi that have been widely used in modern industries for processing traditional fermented foods, industrial enzyme production and organic acids such as fumaric and lactic acid production[12-13......
