Determination of Trace Manganese by Squa

简介：Determination of Trace Manganese by Square-Wave Stripping Voltammetry Shujie Wang， Baoxian Ye＊ Department of Chemistry， Zhengzhou University， Zhengzhou 450052， P. R. China ＊e-mail: yebx@zzu.edu.cn Received: August 6， 2007 Accepted: January 9， 2008 Abstract A novel method of determining trace manganese by square-wave stripping voltammetry with simultaneous plating mercury electrode is described in this paper. Well-defined stripping peaks of manganese are obtained in H3BO4- NaOH buffer (pH 8.0) and peak currents are in good linear relationship with manganese concentrations in two ranges: from 0.36 nM to 36 nM and from 73 nM to 909 nM. The obtained detection limit is 0.18 nM and relative standard deviation is 2.3% (n¼；；；；7) under a predeposition time of 90 s. This proposed method has been used for the determination of trace manganese in real plasma samples with satisfiable results and good matching with the results of graphite furnace atomic absorption spectrometry.
