【摘要】 <正>早自1935年Schevaer和Sucky就对悬汞电极上硒的极谱行为进行了研究,观察到在酸性溶液中Se(Ⅳ)的三个极谱还原波,其后,很多作者报导了各种条件下硒在悬汞电极及其它固体电极上的极谱行为。近来硒对人体和生物的影响日益受到重视,更趋向于测定低含量硒的研究,溶出伏安法更受重视。特别是各种固体电极的使用,但已有的报导对机理论述多限于推测,矛盾之处较多,证据似嫌不足。更多还原

【Abstract】 The cyclic voltammograms of Se(IV)and Se(IV)with metal ions at glassy carbon electrode are studied. All cathodic and anodic peak currents are interpreted with their corresponding electrode reactions; the similarities and differences ofSe(IV) with various metal ions are investigated. The products of electrolysis concentrated on the electrodes ( under suitable conditions ) are examined by x-ray di-ffractions; and proved to be of MSe lattice,compared with the ASTM Standards, Thereby, a theoretical base is provided for the determination of metal ions by cathodic voltammetry as selenides.更多还原
