Abstract:The determination method of tellurium in refined antimony slag by inductively coupled plasma atomic emission spectrometry (ICP-AES) was established. The spectral line of 214.281 nm was used as the analytical line of tellurium. Only La 214.281 nm, V 214.274 nm, Pt 214.250 nm, Nb 214.291 nm and Re 214.297 nm lines had interference. However, the content of La, V, Pt, Nb and Re in refined antimony slag were very low, so their influence could be ignored and the pre-separation was not necessary. After dissolving with aqua regia, the sample solution was directly determined by ICP-AES. The effect of instrumental working parameters on determination results was investigated. The optimal working conditions were as follows: observation height, 15 mm; flow rate of atomizing gas, 0.8 L/min; radio frequency power, 1 300 W. The linear range of method was 0.01-100 mg/L with correlation coefficient of 1.000 0. The detection limit (3σ) was 0.007 2 mg/L. The relative standard deviation (RSD) was 0.16 %, and the recoveries of standard addition were 97 %-102 %.
