| 摘 要： | 采用连续流动分析法测定地表水中高锰酸盐指数,实验测得检出限为0.036 mg/L,并且重点研究了几种不同浓度的高锰酸钾使用液对分析结果的影响,数据证明这其中储备液用量为13.5 ml时的结果最为准确。同时对方法的精密度和准确度进行了验证,并与国标方法(GB 11892-89)进行了比对。

| Abstract: | This study adopts surface water by continuous flow analytical method to determine permanganate index. The experimental detection limit is 0. 036 mg/L. It focused on the influence of different concentrations of potassium permanganate agents. Data shows that the when the dosage of stock solution is 13.5 mL, the result is the most accurate. At the same time, the precision and accuracy of the method is verified, and the results were compared with the national GB 11892- 89 standard.. |
