原子吸收光谱法测定氰化液中的铅

Determination of Pb in Cyanide Solution by AAS

通过对比实验 ,选用柠檬酸钠做络合剂 ,实现了在碱性介质中用原子吸收光谱测定铅的方法。应用该方法测定实际样品的结果与其他方法相符 ,对于 2 .1 9mg/LPb浓度的试液 1 0次测定的RSD为 1 .8%。

A method for determination of Pb in cyanide solution by AAS with citric acid as a masking reagent in basic medium was reported.The method has been applied to the determination of Pb in cyanide solutions.The results are in agreement with those determined with other methods. The precision for the sample with w (Pb)=2.19 mg/L is 1.8% RSD( n =10).
