摘要
利用4种消解方法将电气塑料中的Pb溶解出来,消解液用火焰原子吸收分光光度法测定微量的Pb。通过加标回收率实验,确定其中方法一准确度较高,其测定的加标平均回收率为97.3%～98.9%。
In this paper, four methods were described for the determination of gross Pb in electric plastic with Flame Atomic Absorption Spectrometry. The first method was better in terms of recovery rates. The recovery rate of the first method was between 97.3% and 98.9%.
