摘　　要：针对一种含砷的铟冶金溶液 ,研究了一种选择性硫化除砷方法 ,消除铟生产过程中 As H3对环境的污染 ,考察了酸度、温度、时间及硫化氢加入量等工艺参数对除砷效率的影响 .研究结果表明 :在较佳的工艺条件下 ,砷去除率达 99.1% ,同时铟损失少 ,无二次污染 .Based on an indium containing metallurgical solution,a selective sulfurization precipitation method for eliminating arsenic is studied.It can eliminate the pollution caused by AsH 3 gas produced in the process of producing indium.The effects of acidity,temperature,time and H 2S added amount on arsenic removal efficiency are observed.The results indicate that on better process conditions,arsenic removal ratio can be up to 99.1%, that the method can result relatively lower loss of indium and that it will not bring about second pollution.
