便携式分光光谱仪测定水中氯化物含量

PORS-15浸入式便携分光光谱仪测定水中氯化物,与国家标准方法比对无显著差异。氯化物浓度在0．5～50mg／L范围内与吸光度呈线性关系,线性相关系数为r=0．998,加标回收率97％-106％,测定结果相对标准偏差1．8％～4．1％（n=6）。满足水质监测分析方法中对氯化物测定的限值要求。

The Portable Spectrometer immersion chloride content in water

To use PORS-15 Portable Spectrometer immersion determine the chloride content in surface water,By comparison it has no significant deviation with the national standard method results.To show a good linear relationship between absorbance when the Chloride concentration in the range of 0.5-50mg/L,The linear correlation coefficient is r=0.998.The recovery is 97%-106%,The relative standard deviation of measured results isl.8%-4.1% （n=6）.To content the Limit requirements of Determine chloride about analysis of surface water monitoring.
