摘要
目的:对多参数水质分析仪法与国标法测定水中游离余氯进行对比研究。方法:采用氯标准溶液对多参数水质分析仪的内置工作曲线进行验证,采用加标回收实验对多参数水质分析仪法进行测试。结果:多参数水质分析仪工作曲线准确可靠,回收率在80.0%~95.0%,精密度在0.38%~6.24%,符合标准要求。结论:与国标法相比,多参数水质分析仪法检测速度更快,精密度更高,适用于生活饮用水中游离余氯的快速检测。
Objective:To compare the determination of free residual chlorine in water by multi-parameter water quality analyzer method and national standard method.Method:The built-in working curve of the multi-parameter water quality analyzer was verified by chlorine standard solution,and the multi-parameter water quality analyzer method was tested by recovery test.Result:The working curve of the multi-parameter water quality analyzer was accurate and reliable,with a recovery rate of 80.0% to 95.0% and a precision of 0.38% to 6.24%,which met the standard requirements.Conclusion:Compared with the national standard method,the multi-parameter water quality analyzer method has faster detection speed and higher precision,and is suitable for the rapid detection of free residual chlorine in drinking water.
