Abstract
In this study, the extraction of dysprosium was investigated using a supported liquid membrane (SLM) system. The experiments were performed using bis (2, 4, and 4-trimethylpentyl) phosphinic acid (Cyanex272) as the carrier. The effect of various parameters such as stirrer speed, feed phase pH, extractant concentration, initial metal concentration and membrane pore size on dysprosium transfer was studied. The highest membrane permeability was obtained with Cyanex272 at concentration of0.6 M and initial pH of the feed phase equal to 5 and stripping phase concentration of 1 M. Under optimal conditions, the membrane permeability of 2.15×10-5 m s-1 was obtained. Examination of SLM stability showed that the membrane used was stable for 6 periods (3 days) and permeability did not change significantly
