摘要
样品经硝酸分解 ,用高氯酸冒烟氧化分离锰后 ,铅在盐酸底液中 ,在峰电 -0 6V处产生一良好的还原波 ,能直接测定电解金属锰中微量铅 ,且方法简便、快速、准确 ,回收率在 98 4 0 %～1 0 0 60 % ,相对标准偏差 3 3 1 %～ 4 1 0 % ,能应用于工业控制分析。
After the sample was digested by hydrogen nitrate and the manganese′ oxygenolysis by perchloric acid smoking, the lead in hydrochloric acid liquid generates a good reducing wave when the peak voltage is -0 6 V. The method can directly determine the trace lead in electrolysing manganese and is a simple, fast and accurate way, which can be applied in industry analysis. The recovery rate is between 98 4% and 100 60% and the relative standard deviation is between 3 31% and 4 10%.
