英文摘要 | 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.; 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.; This work was supported by National Science Foundation of China (Nos. 20975022 and 21275030) and The National Key Technologies R & D Program of China during the 12th Five-Year Plan Period (Key technology of quality and safety control during aquatic product processing, No. 2012BAD29B06).; This work was supported by National Science Foundation of China (Nos. 20975022 and 21275030) and The National Key Technologies R & D Program of China during the 12th Five-Year Plan Period (Key technology of quality and safety control during aquatic product processing, No. 2012BAD29B06).; 作者联系地址:福州大学 化学学院,食品安全分析与检测教育部福建省重点实验室,福建 福州 350002; Author's Address: Key Laboratory of Analysis and Detection Technology for Food Safety, Ministry of Education, Fujian Provincial Key Laboratory of Analysis and Detection for Food Safety, College of Chemistry and Chemical Engineering, Fuzhou University, Fuzhou 350002, China; 通讯作者E-mail:jjsun@fzu.edu.cn |
