浸入式便携分光光谱仪测定水质甲醛含量方法研究

研究PORS-15浸入式便携光谱仪测定水甲醛含量的方法,甲醛含量在0.03～2mg/L范围内与吸光度呈良好的线性关系,加标回收率为93%～95%,测定结果与国家标准方法测定结果比对无显著差异。满足水质监测分析方法中关于甲醛的限值要求。

To study the methods of PORS-15 Portable Spectrometer immersion determine the formal dehyde content in water,It shows a good linear relationship between absorbance when the formal dehyde content in the range of0.03～2mg/L,The recovery is 93%～95%,the measured results has no significant deviation with the national standard method results.It satisfies the Limit requirements of formal dehyde about analysis methods in Water Quality Monitoring.
