镍和钴对人的健康有着密切的关系,人发中的微量元素往往能很好地反映出人的健康状况。电化学方法中测定痕量元素有效的阳极溶出伏安法由于镍和钴在汞中的溶解度很小而无法应用。最近报导了利用镍(Ⅱ)-丁二肟(Ni(Ⅱ)-DMG)的螯合物Ni(Ⅱ)A_2在悬汞电极(HMDE)上吸附富集的伏安法测定了水、生物物质和食品中的镍。用线性
Nickel and cobalt are closely related to human health, trace elements in human hair can often well reflect the human health. Determination of Trace Elements in Electrochemical Methods Effective anodic stripping voltammetry can not be applied due to the small solubility of nickel and cobalt in mercury. Recently reported the use of nickel (Ⅱ) - butanedioxime (Ni (Ⅱ) -DMG chelate Ni (Ⅱ) A_2 adsorbed on the hanging mercury electrode (HMDE) by voltammetry determination of water, biological substances And in the food of nickel. Use linear
