  author={Du Yuanyuan},
A method with prior AgCl precipitates for the determination of zinc impurity in high-purity silver by inductively coupled plasma atomic emission spectrometry(ICP-AES) was reported.Spectral interferences of Cr,Cu,Fe,Ni and Ti to Zn at specific wavelengths have been investigated.The spectral coincidence profiles were recorded and interfering lines were identified.The optimum analytical line was Zn 206.200 nm {163}.It was necessary to correct spectral interferences at Zn 213.856 nm {157} and Zn… CONTINUE READING
