Abstract：The establishment of detection method for Te in calaverite has important significance for the genetic study of calaverite ore deposit as well as the comprehensive development and utilization of gold ore sources.The sample was treated by NaOH-Na2O2 alkali fusion method. 125Te+ was selected as the determination objective. The mass spectrometry interference of 85Rb40Ar+ and 109Ag16O+ with the determination of 125Te+ was corrected by mathematical correction equation. 10.0ng/mL 103Rh was selected as the internal standard. The determination of Te in calaverite by inductively coupled plasma mass spectrometry (ICP-MS) was realized.The sample treatment methods were selected. Meanwhile, the dosage of Na2O2 was optimized and 0.1g NaOH-0.6g Na2O2 was finally used for sample treatment. The influence of sampling depth on the signal intensity of Te and Rh as well as the double charge yield (Ba2+/Ba+) and oxide yield (CeO+/Ce+) was discussed. The sampling depth was 150-step. The effect of ethanol concentration (0-6%, volume fraction, the same below) in testing solution on the signal intensity of Te was investigated. The results showed that 3% ethanol had significant enhancing effect on mass spectrometry signals. The linear range of method was 0.020-200μg/g. The correlation coefficient of calibration curve was 0.9999. The detection limit and low limit of determination was 0.015μg/g and 0.049μg/g, respectively. The certified reference materials of calaverite (GBW07858 and GBW07859) were used for method validation. The found results were consistent with the certified values. The relative standard deviations (RSD, n=12) were between 2.6% and 5.9%. The recoveries were between 92% and 108%. The proposed method was applied to the analysis of actual calaverite sample, and the found results were consistent with those obtained by hydride generation-atomic fluorescence spectrometry (HG-AFS)
