摘　　要：研究建立采用连续流动分析法测定水中高锰酸盐指数的分析方法，方法的检出限为0.04 mg/L，测定范围为0.16-10.0 mg/L。实验表明测得的数据与采用国家标准方法测得的数据有较好的一致性，并且已应用于实际样品测定，结果令人满意。具有操作简单、灵敏度高、分析速度快、稳定性高且易于实现自动化分析。This study established the analytical met hod for determination of permanganate index of water by continuous flow analysis. A detection limit of 0.04 mg/L CODMn with a determination ranged from 0.16 to 10.0 mg/L for its theoretical CODMn was obtained under the experimental conditions. The data obtained by the present method were fairly in good agreement with those obtained by the national standard method. It has been applied to determine real samples with satisfactory results. This method for determining CODMn was simple, rapid, stable and suitable for automatic analysis.
