Abstract

In this research, extraction of cobalt ions from non-aqueous medium was carried using Aliquat336 extractant. The effect of different parameters on the non-aqueous extraction process including ethylene glycol concentration, extractant concentration, hydrochloric acid concentration and cobalt ions concentration in aqueous solution was investigated using the experimental design approach. According to the desirability of one and the maximum extraction efficiency of cobalt ions, the optimal conditions include volume percentage of Aliquat336 (19.2%), cobalt concentration (899.4 ppm), volume percentage of ethylene glycol (65.3%) and hydrochloric acid concentration (7.81 M) were obtained. The validity of the data was observed with minimal error between the predicted data (94.82%) and the experimental data (99.36%).
