摘要
试样以硝酸、氯酸钾分解、硫酸冒烟,再以碘量法测定锌精矿中的砷含量。方法准确、简便,加标回收率为98.20%-101.6%,RSD<2.0%,方法测定范围0.20-3.00%。
The samples were decomposed bynitrie acid,potassium chlorate and sulfuric acid. The eontentsof arsenic were determined by iedimetric method. The method was simple andaccurate. Recoveries were in the range of 98.20 -101.60% and RSD＇s were found to be less than 2.0%. The measurement range of this method was 0.2 - 3.0%.
