Simultaneous Determination of Arsenic, Antimony and Bismuth in Chemical Materials by Inductively Coupled Plasma Optical Emission Spectrometry

Abstract

Arsenic, antimony and bismuth in gold ores were simultaneously determined by inductively coupled plasma optical emission spectrometry (ICP-OES) with spectral lines of 188.980, 206.834 and 223.061nm as analytical line respectively, under preset instrumental parameters. The linear range of the method for arsenic, antimony and bismuth was 0~80ug/mL and the correlation coefficient was greater than 0.99995. The detection limit for arsenic, antimony and bismuth was 2.87, 1.63 and 0.84ug/g respectively. The results of this method are consistent with the national standard method, and the relative error is less than 1.5%. The relative standard deviation (RSD) of this method is better than 5.0% (n=11) with good accuracy and precision. ICP-OES can be used for simultaneous determination of multiple elements and is suitable to the analysis of large quantities of samples.

Arsenic Determination in Geological Samples by Atomic Fluorescence Spectrometry

“…It is well known that As at trace and ultra-trace level can be determined by AAS, ICP-AES , ICP-MS , ICP-OES and CVG-AFS [1][2][3][4]. AFS was the most frequently-used analytical method in China because it had a wide linear range, high sensitivity, low background noise, convenient operation, and low cost.…”
