火焰原子吸收法测聚合氯化铝中铅

Determination of Pb in PAC by Flame Atomic Absorption Spectrometry (FAAS)

建立了一种以硫酸-硝酸对样品进行消化,火焰原子吸收测定铅的方法。该法用于实际样品的测定时,相对标准偏差小于2.3%,加标回收率为98%～102%。该方法已成功地用于实际样品中的铅的测定,效果良好。

A method is established for the determination of Pb in PAC by flame atomic absorption spectrometry (FAAS). The sample was digested by H2SO4-HNO3 before determined. The relative standard deviations of the method were generally lower than 2.3 %, and the recovery ratios were 98 %～102 %.The application of the method to the determination of Pb in real sample was tested and satisfactory results were obtained.
