优化了传感分析中脉冲频率和尺寸、支持电解液p H值、沉积电位、沉积时间等参数。锌离子浓度与溶出峰电流值在50

00μg/L范围内呈线性关系

Abstract

A rapid

easy

environmentally friendly and sensitive anodic stripping voltammetric method with a bismuth in-situ modified boron-doping diamond（ BDD） electrode is developed for the determination of Zn（ II）ion. In presence of bismuth ion

the sensitivity for the determination of Zn（ II） is remarkably enhanced. Effect parameters such as scan mode

bismuth concentration

boron-doping concentrations of BDD electrode

pulse size

pulse frequency

p Hs

preconcentration potential and time are investigated. Under the optimal conditions

the stripping peak currents increase linearly with increasing concentrations of Zn（ II） ion in the range of 50

00 μg/L. Correlation coefficient is 0. 9979

limit of detection is 2. 32 μg/L

for Zn（ II） ion（ S/N = 3）. The interference experiments show that common ions have little influence on the determination except Cu（ II） ion. The electrode displays a good repeatability.
