摘要
采用离子选择性电极和电位恒定的参比电极为敏感头,和高输入阻抗、高精度的电位计组成传感器,通过数据采集卡(DAQ)以及以LabVIEW为开发平台的虚拟仪器,实时在线监测水体中CN-、F-、Cl-、Ca2+、Mg2+、S2-等多种离子含量,为水质污染的在线监测提供了一种具有理论指导意义和实用价值的新方法。
The sensors were made of ions selectivity electrodes and voltage invariable standard electrodes as the probe, high input impedance and high precision potentiometers. By using the virtual instrument constructed by data acquisition and LabVIEW-based technique, the timely concentration of ions in polluted water could be measured, such as CN^-,F^-,Cl^-,Ca^2＋,Mg^2＋,S^2-, etc. It provides a theoretic guidance and practical application for the online measurement of polluted water.
