摘要
炼锌废渣中的锌、铁、铜、铅含量分别用化学分析法和原子吸收法进行测定,试验结果表明炼锌废渣中含有锌(1.97%)、铁(6.68%)、铅(10.79%)。用两种方法测定可以看出,原子吸收法的相对偏差小于28.67%,化学分析法的相对偏差小于0.85%。相比之下原子吸收法准确度高、操作简便、测定速度快,但精确度差;化学方法准确度差,但精确度高。
Zinc smelting waste residue of zinc, iron, copper, by chemical analysis method and atomic absorption spectrometry were measured. The experimental results show that the zinc slag containing zinc(1.97%), iron(6.68%), lead(10.79%) The relative deviation of the atomic absorption method is less than 28.67%, and the relative deviation of the chemical analysis method is less than 0.85%, simple operation, fast determination, but the accuracy is poor, chemical method is poor, but the accuracy is high.
