摘要
在pH=8～9的NH_3·H_2O—NH_4Cl—磺基水杨酸—丁二肟介质中,Ni^(2+)在-1.09V(vs.SCE)处出现还原峰,Ni^(2+)含量在0～50μg/m1范围内,峰电流与浓度呈线性关系,体系选择性强,有效消除大量Fe^(3+)和一定量Cu^(2+)、Zn^(2+)对测定的干扰。
In the base liquid of NH3 ?H2O. NH4C1,5 - sulfosalicylie acid 2 - 3 - butaneclionedioxime. pH value was obtained. Its peak potential was ENi = ~1.09V(vs. SCE). The peak current changed linearly with the concentration of Ni in the range of 0~50g/50ml.
