摘要
分析了GB11892 - 89和ISO846 7- 1986两种测定水中高锰酸盐指数的方法 ,得出 :前者操作较简单 ,但耗时多 ;后者耗时少 ,但操作复杂。因两者的反应原理相同 ,为此 ,将两法的缺点摒弃取其优点结合 ,在准确度和精密度都达到水环境监测要求的前提下 ,得到一个既省时间 ,操作又简单的方法 ,使工作效率得到提高 。
Two methods of determining the index of permanganate in water,GB11892-89 and ISO8467-1986,were analyzed here.The former has the features of less brief operation and longer time,the latter has the features of less time and complex operation. Because of their the same reaction principle, the author combined with their advantages and spurned their shortcoming, expounded a method that needs less time and brief operation to meet the need of onerous water quality supervision work.
