Abstract：A microwave plasma atomic emission spectrometry(MP-AES) for the determination of Cu, Pb, Fe, Cd, Mn in zinc oxide produced by direct process with microwave plasma atomic emission spectrometer was established. The sample was dissolved with a mixtare of nitric acid and hydrochloric acid by heating at low temperature. The spectral lines of Cd 228.802 nm, Cu 324.754 nm, Fe 259.940 nm, Mn 403.076 nm and Pb 405.781 nm were selected as analytical lines. The matrix of zinc did not interfere in the determination of those elements within selected amount of sample. The relative standard deviation for the determination of each element in the sample of ZnO-1 was between 0.91% and 4.9%, and the standard addition recovery was between 90% and 116%. The determination results were consistent with those obtained by national standard and ICP-AES methods. The established method was suitable for simultaneous determination of multi-element in zinc oxide produced by direct process.
