摘要
研究了二乙基二硫代氨基甲酸钠（ＤＤＴＣ）体系中，方铅矿与ＤＤＴＣ的作用形式和机理。ＤＤＴＣ在方铅矿表面形成二乙基二硫代氨基甲酸铅（ＰｂＤ２），并牢固地吸附在其表面。采用一系列电化学测试技术和计算机模拟，研究方铅矿表面的电化学反应以及吸附态物质。
The electrochemistry characteristics of galena in sodium diethyldithiocarbamate(DDTC) medium was studied.Lead diethyldithiocarbamate was formed and adsorbed on galena surface.The adsorbed products on galena and the relationship between electrode potential and coverage of the adsorbed products were examined by electrochemical technique and computer modeling.Galena is subjected to strong oxidation in alkaline medium (pH=11～12).however.the oxidation is retarded in the presence of DDTC.
