Voltammetric determination of Pb²⁺ and Cd²⁺ with montmorillonite-bismuth-carbon electrodes

Luo, Liqiang / Wang, Xia / Ding, Yaping / Li, Qiuxia / Jia, Jianbo / Deng, Dongmei

AbstractThe simultaneous determination of trace amounts of Pb²⁺ and Cd²⁺ with montmorillonite-bismuth-carbon electrodes was developed. Several parameters affecting the stripping current response were investigated and optimized. Under optimal conditions, the modified electrode showed a good linear response to Pb²⁺ and Cd²⁺ in the concentration range from 1 to 24μgL⁻¹. The detection limits were 0.2μgL⁻¹ for Pb²⁺ and 0.35μgL⁻¹ for Cd²⁺. The proposed method was applied for determining Pb²⁺and Cd²⁺ contents in real water samples.
