[Determination of lead in tinplate by ICP-AES].
The determination of lead in tinplate by ICP-AES was presented in this paper. The tinplate samples were pretreated with NaOH-H2O2 for dissolving tin and lead,and the spectral interferences from iron could thus be avoided. The lead content in the sample was determined in the range of 0.14-0.38 microg/cm2. The recovery and the relative standard deviation (RSD) were in the ranges of 96.1%-103.2% and 2.6%-3.8%, respectively. The method was simple,rapid and efficient.
