摘要
铜冶炼过程中产生含砷的废渣,这种渣中的砷在溴化钾和硫酸联胺存在下能定量的溶解于1∶1HCl中。本文据此对"GB/T3884.9-2000溴酸钾法测定砷量"进行了简化。简化后适用于这种砷渣中砷的测定。
While producing copper, there can come out some wastes containing arsenic. The wastes can be completely dissolved in 1 ： 1 HCl under the existence of KBr and N2H4 · H2SO4. According to this, the paper simplifies ＂the GB/T 3884.9-2000＂. The simplified method can determine the arsenic in the wastes.
