摘要
研制了一种基于光度法现场测定水中余氯、总氯的手持式仪器 ,开发了相应的专用试剂包 ,讨论了影响该仪器分析性能的主要因素。用该仪器和试剂现场测定水中的余氯和总氯 ,线性范围是 0 .0 1～ 5 .0mg/L ;RSD <3% ;单个样品分析时间不超过 3min。
A new portable free/total chlorine analyzer and the unique reagent package for in-situ analysis were developed. The linear range for the determination of free chlorine and total chlorine was 0.01～5 mg/L, the RSD was <3%, the average time for one sample analysis was 3 minutes. This analysis was applied to determine the free and total chlorine in water with result.
