Multi-Element Determination in Chalcopyrite by Inductively Coupled Plasma Atomic Emission Spectrometry

Song-jun Wang, Ping Chang, Wang Pu-jun, Hou Tian-ping

Abstract

A method for simultaneous determination of Cu, Fe, Cd, Co, In, Mn, Ni, Pb and Zn in chalcopyrite by inductively coupled plasma atomic emission spectrometry (ICP-AES) is developed. Samples are dissolved by HCl-HNO_(3) and directly determined by ICP-AES. The interferences from Fe and Cu in the samples on trace analytes are eliminated by using correction coefficient method. The method has been used in determination of these elements in national geostandard sample (GBW 07268). The relative errors (RE) for all these elements except Ni are less than 5.00% with precision of 2.55%～7.62%RSD (n=8).
