Abstract

Solvent extraction is one of the effective methods for extracting copper and nickel from aqueous solution of pregnant liquid solution. This research is mainly based on direct solvent extraction method. The effect of extraction of D2EHPA on extraction of copper and nickel ions in synthetic solution has been investigated. In this study, by changing the levels of parameters such as speed and time of mixing, concentration of extractor, acidity (pH) and temperature were determined to extract copper and nickel from synthetic solution. It should be noted that, in this synthetic solution, the amount of copper was 770 ppm, nickel 3200 ppm, iron 800 ppm, and 200 ppm. The results of the experiments showed that the best and highest extraction of copper and nickel ions at 5 min, speed of 700 rpm, temperature= 45 ° C, extractor concentration= 30% and ratio A / O = 3 at pH = 6.
