Inductively Coupled Plasma-Atomic Emission Spectrometric Determination of Silver,Arsenic,Lead and Zinc in Copper Concentrates

A method for the determination of silver,arsenic, lead and zinc in copper concentrates by inductively coupled plasma-atomic emission spectrometry has been applied.Matrix effect can be eliminated by using the matrix matching method.The interferences among the detected elements are not significant.The method has been applied to the determination of certified Reference Materials and practical samples and the analytical results are in good agreement with the certified values and those from other methods.The recoveries of the method are 87%～95% for Ag,91%～103% for As,92%～110% for Pb and 88%～108% for Zn with precision of 0.55%～1.52%RSD(n=12).Compared with the present single-element analytical technologies,the proposed method is rapid and can meet the requirements for commodity inspection of copper concentrates and can be applied to routine inspection.
