聚合氯化铝中铅测定的改进

Improvement of the method for Determination of pb Contained in PAC

为了得到更高的回收率及精确度 ,使用石墨炉检测水处理剂聚合氯化铝中铅含量 ,且在样品中加入基体改进剂及信号稳定剂。

In order to gain higher recovery rate and accuracy, atomization in graphite tube furnace was used in determination of lead in water treatment chemicals-PAC, matrix modifier and signal stabilizer were added to the sample. It was proved that this measure gave better determination results.
