摘要
In the present work depollution of residual acid waters containing cadmium ions is presented. For depollution the tributylphosphate (TBP) as extractant has been used. The cadmium ions are very toxic and must be extracted from acid waters before their neutralization or recyclation. Different parameters affecting the extraction of cadmium ions as hydrochloric acid concentration and water-extractant rate have been studied. The obtained results put in evidence the big influence of hydrochloric acid concentration on cadmium extraction degree. The increasing of the HCI concentration determines the increasing of distribution coefficient.
