摘要
An electrochemical hydricle generation system was developed for the detection of Te by coupling an electrochemical hydride generator with atomic fluorescence spectrometry. Since TeH2 is unstable and easily decomposes in solution, a reticular W filament cathode was used in the present system. The TeH2 generated on the cathode surface was effectively driven out by sweeping gas from the cathode chamber. In addition, a low temperature electrochemical cell (10 degrees C) was applied to reduce the decomposition of TeH2 in solution. The limit of detection (LOD) was 2.2 ng ml(-1) and the relative standard deviation (RSD) was 3.9% for nine consecutive measurements of standard solution. This method was successfully employed for determination of Te in soldering tin material. (c) 2008 Elsevier B.V. All rights reserved.
