水处理剂聚合三氯化铝中微量铅的测定

Determination of Trace Amount of Pb in Water Treatment Chemicals Polyaluminum Chloride

在酸性条件下 ,聚合三氯化铝中的微量Pb2 + 与外加的Bi3 + 一道用Na2 S能形成沉淀 ,用火焰原子吸收分光光度法分离检测出聚合三氯化铝中铅的含量。

It was reported that the Pb 2+ in polyaluminum chloride was co-precipitated by Bi 3+ in a acid solution with Na 2S, the content of Pb 2+ was determined by flame atomic absorption spectrophotometry. This method has higher recovery rate and accuracy.
