Catalytic electroreduction of nitrite ion in presence of thioglycolic acid in ammonium acetate buffer medium shows the possibility of devising an analytical method for determination of nitrite at low concentration. A wide linear range of 0.9-9 μg/mL is achieved. The limit of quantification is found to be 0.7 μg/mL using differential pulse polarography method. The method has been successfully applied for the analysis of nitrite content in marine waters and industrial wastes.

伏安法测定不同基质中亚硝酸盐的方法开发

在乙酸铵缓冲介质中存在巯基乙酸的情况下，亚硝酸根离子的催化电还原显示了设计一种测定低浓度亚硝酸根的分析方法的可能性。实现了 0.9-9 μg/mL 的宽线性范围。使用差分脉冲极谱法发现定量限为 0.7 μg/mL。该方法已成功应用于海水和工业废物中亚硝酸盐含量的分析。
