Determining the optimal amount of D۲EHPA and TBP extractants in the solvent extractionof nickel and cadmium from the filter cake of cold purification of zinc production factory.

Solvent extraction is widely used and on a commercial scale as a method with selective extraction inthis study, we try to achieve the highest amount of cadmium and nickel extraction from the cadmium coldpurification cake filter by using the optimal amount of the combination of D۲EHPA and TBP extractors. Differentquantities of extractors were examined and tested. The highest amount of extraction in of D۲EHPA = ۲۲.۵ ml,TBP = ۷.۵ ml and ۴۰۲ = ۲۰ ml. It is done with ۵۰ ml of distilled water and the ambient temperature was achievedunder rotation and at PH=۸-۹ in time = ۳۰ min.Write your abstract here, not more than ۵۰ words.
