生活饮用水中游离性余氯测定条件优化研究

Researches on the optimization of determinating conditions of free residual chlorine in drinking water

结果：池水温度、尿素、游离性余氯、PH值的合格率分别为2.8%、68.1%、92.4%、94.4%，浑浊度、细菌总数、大肠菌群合格率为100%，有5个游泳池尿素严重超标。

Results : Yield of temperature or carbamide or residual chlorine or ph valve is 2 . 8 % , 68 . 1 % , 92 . 4 % , 94 . 4 % .

并且联用处理最终游离性余氯含量较多，可以保持持续的消毒效果。

There were more free chlorine remained in the combination treatment .

分别在含有无机盐、有机物、游离性余氯的洗涤水中，试验各因素对预镀铜层表面质量的影响。

The influences of each factor in rinsing water respectively containing inorganic , organic substance and residual free-chloric on the surface quality of strike copper deposits were studied .

经水样监测指标相关性和灰色关联性分析，认为游离性余氯可作为常规监测高层住宅二次供水质量的代表性指标。

After the relative analysis by statistics , it was thought that Free Residual Chlorine to be a representative water characteristic for routine monitoring of water quality of the high building .

在此条件下，测定三种生活饮用水游离性余氯，回收率在96.7%～99.8%，测定结果与《生活饮用水标准检验法》37.3滴定法颇为一致。

Under these conditions , the recovery rate of the free residual chlorine in three water samples are 96.7 % to 99.8 % . These results are very consistent with Drinking Water Standardized Testing Method 37.3 Titrimetric Analysis .

与之相比，高层建筑二次供水浑浊度（82.26%），游离性余氯（80.65%），细菌总数（83.06%）等指标合格率明显偏低（χ2检验P<0.01）。

Comparatively , the qualification rate of secondary water supply of high building was significantly low , turbidity ( 82.26 % ), free residual chlorine ( 80.65 % ), and the total bacterial count ( 83.06 % ) were the most unqualified items ( P < 0.01 ) .
