摘　　要：长江地面水在产水期呈黄色浑浊状态。按GB11892 -89进行高锰酸盐指数分析。滴定时 ,由于受剩余悬浮物的干挠 ,水样呈浅黄色。因而滴定终点微红色极难判断。通过本文描述方法改进后 ,滴定时样品为无色滤液。滴定终点微红色非常明显。提高了滴定分析的准确度。The Surface water in the Yangtze River is in a yellow muddy state during flood seasons The permanganate index is analysed according to GB11892-89 When titrated, the water appears light yellow as a result of the disturbance of the remaining suspended substances, so it is extremely difficult to determine whether the titrating terminal point is of reddish After the improvement described in the paper, the water appears colourless when titrated It is easy to see that the titrating terminal point is of reddish, thus the accuracy of the titration analysis is raised
