根据国家环境标准样品协作定值的任务要求，采用酸性高锰酸钾氧化法（GB11892—89）测定了编号为2031—12C和2031—12D两个环境标准样品的高锰酸盐指数，结果分别为2．84mg／L和3．43mg／L，均在考核要求范围内，且与标准值2．82mg／L和3．39mg／L较为接近。两组测定结果的相对标准偏差分别为2．36％和5．66％，相对误差分剐为0．71％和1．18％，均符合质量控制要求。提出了经国家环境保护部标准样品研究所考核验证，两个标准样品的测定结果均合格并被采用。

In this article, the permanganate index of two environmental standard samples (the determination numbers are 2031--12C and 2031--12D) are determined by acid potassium permanganate oxidation method (GB 11892--89), according to the requirement of national environmental standard collaboration fixed value. The results are 2.84mg/L and 3.43mg/L respectively, which are both within the range of assessment requirements and close to the standard value 2.82mg/L and 3.39mg/L. The relative standard deviation of the two groups of results are 2.36% and 5.66% respectively and the relative error are 0.71% and 1.18%, which all meet the requests of quality control. After the assessement and validation by the national institute for environmental reference materials, the results of the two environmental standard samples are qualified and adopted.
