Determination of Elements of Cu,As,Pb,Cd and Hg in Different Pocessed Products of Pyrite

Abstract:

Objective:To establish a method for the determination of 5 elements (As, Pb,Cu,Cd and Hg) in different pocessed products of pyrite by inductively coupled plasma atomicemission spectrometry/mass spectrometry(ICP-AES/MS), in order to provide a basis for thelimit standards of As, Pb,Cu, Cd and Hg and other harmful elements. Method: Five elements of the digested samples were determined by ICP-AES/MS simultaneously, and the contents were calculated by calibration curves. Result: Good linearity of calibration curves was obtained for ICP-AES/MS assay, the accuracy and the recovery met the requirement of trace analysis. Conclusion: The method is highly sensitive,rapid,accuracy and offered with low LOD.
