摘要/Abstract

摘要： 在铅笔芯上通过实时沉积锑薄膜，使用方波阳极溶出伏安法（SWASV）对Cd(II)和Pb(II)进行同时检测. 沉积时间为180 s时，Cd(II)和Pb(II)的最低检测限分别为0.075 g.L^-1和0.13 g.L^-1，较铋膜修饰的铅笔芯电极低. 在低pH值溶液（pH 2.0）中重现性好. 该电极可成功用于测定自来水中的Cd(II)和Pb(II)含量.

关键词: 锑膜电极, 阳极溶出伏安法, 重金属离子, 铅笔芯电极

Abstract: In this paper, a pencil core was used as the substrate for an antimony-film electrode for simultaneous detection of Cd(II) and Pb(II) by square-wave anodic stripping voltammetry (SWASV). With the deposition time of 180 s, the low limit of detection (LOD) for the electrode was determined to be 0.075 ?g?L-1 for Cd(II), while 0.13 ?g?L-1 for Pb(II) with good reproducibility in low pH solutions (pH = 2). The results show a much lower LOD than that of bismuth-film pencil core electrode. Finally, this antimony-film electrode was successfully applied to determine Cd(II) and Pb(II) in tap water.

Key words: antimony film electrodes, anodic stripping voltammetry, heavy metal ions, pencil core electrode
