摘要
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.
