摘　　要：结合水质监测工作实际情况,根据GB 11892-1989《水质高锰酸盐指数的测定》,对不同加热时间和加热后不同保存温度及保存方式对高锰酸盐指数测定结果的影响进行探析。由实验结果可知,在沸水浴中的加热时间和沸水浴后的样品保存方式对检测结果的影响较大,决定了整个实验过程的成功与否。根据实验结果探析了影响高锰酸盐指数测定结果的关键因素,并针对相应因素研究解决办法,对水质高锰酸盐指数的检测过程中关键点的把控和出现问题的查找具有指导意义。Combined with the actual situation of water quality monitoring and according to GB 11892-1989 determination of permanganate index of water quality,the effects of different heating time,different storage temperature and storage mode after heating on the determination results of permanganate index are analyzed.It can be seen from the experimental results that the heating time in the boiling water bath and the sample storage mode after the boiling water bath have a great influence on the test results,which determines the success of the whole experimental process.According to the experimental results,the key factors affecting the determination results of permanganate index are analyzed,and the solutions are studied according to the corresponding factors,which has guiding significance for controlling the key points and finding the problems in the detection process of water permanganate index.
