| Abstract: | The thermodynamics study on arsenic removal from cobalt solution with sulphur precipitation method was performed. The contents changes of various arsenic complexes in cobalt solutions were studied. The distribution curve for ion containing arsenic in As-S-H2O varies with pH value and sulphur dosage at 25℃ was drawn. The effects of process parameters on arsenic removal were tested. And the study result shows that pH value and sulfiriz- ing agent dosage influences residual arsenic content in solution greately, and the control of sulphur adding amounts is benefits to form As2S3 precipitation with arsenic containing compounds in solution. |
