The method was developed for the multi-element analysis of high-purity Te. The matrix was volatilized through the reaction of Te with chlorine gas, which was obtained by the electrolysis of hydrochloric acid. The behavior of 61 trace elements during Te chlorination at 200–270 °С was studied. The maximum number of trace elements (39) quantitatively remained in the concentrate at a volatilization temperature of 240 °С. Trace element concentrations were determined using inductively coupled plasma optical emission spectrometry (ICP-OES). The limits of detection (LODs) of the 39 trace elements were 0.2–30 ng g–1. The possibility of reaching lower trace element LODs was demonstrated. For Ag, Cd, Mn, and Pd, the LODs were reduced by 3–25 times by using electrothermal atomic absorption spectrometry (ETAAS), with trace element LODs of 0.04–2 ng g–1. The accuracy of the matrix chemical volatilization procedure was evaluated using spike experiments. Recovery rates ranged from 80 to 120%. The analysis of a Te sample with unknown composition using ICP-OES and ETAAS methods after the proposed matrix chemical volatilization procedure gave comparable results to those obtained by ICP-OES without volatilization.",
