| 摘 要： | 研究了应用硫氰酸钾与铜离子加热反应生成硫氰酸亚铜沉淀而分离出硫酸铜中的基体铜,并用钼蓝分光光度法测定硫酸铜样品中微量砷的方法。试验结果表明相对标准偏差（RSD）小于3．6％。本方法所需设备与化学试剂较为常见,成本较低,操作上容易实现,而且测试过程中不会产生剧毒的砷化氢气体。

| Abstract: | The heating reaction of potassium thiocyanate and the ion of copper to produce copper thiocyanate precipitation,was used to isolate the matrix of copper,and molybdenum-blueness spetrophotometric method was chosen to determine the trace arsenic in copper sulfate sample.The experimental results show the relative standard deviation(RSD) is less than 3.6%.The required reagents of this method is common,and the the cost is low,the operation is easy,and no poisonous hydrogen arsenide is produced in the experiment. |
