水中硝酸根含量的实时监测是一个亟待解决的现实问题,为了满足硝酸根监测的实时性要求,避免采样、预处理等繁琐的步骤,提出了一种新型的原位监测硝酸根传感器系统的研究设计,介绍了系统的工作原理和构成,该仪器利用双光束单波长标准测量法,不仅能有效消除材料及粒子散射对测量的干扰,而且简化了设计结构。并用紫外分光光度计进行了模拟实验,实验证明,这种新型的传感器系统能够满足指定水域的硝酸根实时监测要求。
The real-time monitoring of nitrate content in water is a real-time problem that needs to be solved urgently. In order to meet the real-time requirements of nitrate monitoring and avoid the tedious steps of sampling and pretreatment, a new type of nitrate sensor system The principle and composition of the system are introduced. By using the double-beam single-wavelength standard measurement method, the instrument can not only effectively eliminate the measurement interference caused by the scattering of materials and particles, but also simplify the design structure. Experiments with UV spectrophotometer show that the new sensor system can meet the real-time monitoring of nitrate in the specified waters.
