摘　　要：利用方波溶出伏安法(SWASV)与扫描电子显微镜(SEM)系统研究了Pb(Ⅱ)阳极溶出峰形的影响因素,确定了电极材料、Pb(Ⅱ)浓度和沉积时间及电沉积形貌对Pb(Ⅱ)阳极溶出峰峰形的影响.研究结果表明Pb(Ⅱ)浓度和沉积时间对其阳极溶出峰峰形具有类似的影响,而电极材料暴露的不同晶面影响Pb(Ⅱ)的阳极溶出峰.此外,Pb(Ⅱ)的阳极溶出峰的峰形与沉积到电极表面Pb的尺寸有很大的关系.以上所获得的研究结果对Pb(Ⅱ)的电沉积及对Pb(Ⅱ)的准确检测提供了科学的指导.The influence factors of the Pb（Ⅱ）＇s anodic stripping peak shape were studied systematically using square wave stripping voltammetry electrochemical method,and electrode material,Pb（Ⅱ）concentration and deposition time were determined to have certain influence to the anodic stripping peak shape of Pb（Ⅱ）,among these factors,the concentration and deposition time had a similar influence to the striping shape of Pb（Ⅱ）,and the influence of electrode material might depend on the crystal effect.In addition,the peak shape of the anodic stripping peak of Pb（Ⅱ）has a great relationship with the size of the electrode surface deposited Pb.The obtained research results provide a scientific direction to electrochemical deposition and trace detection of Pb（Ⅱ）.
