基于两电极体系的水质检测分析平台设计

为实现对水质的多参数检测,设计了一个基于两电极体系的水质检测分析平台。该检测平台通过最小化极化电流的思想,采用辅助电极面积远大于工作电极的电极参数,设计了基于两电极体系的集成电极和软硬件系统,摈弃了传统三电极体系的参比电极,同时克服了传统三电极体系容易污染样品的缺点,能实现电化学工作站的诸多功能。本研究在该检测平台上开展了水样的电导率(EC)、pH和重金属浓度的检测研究,获得了较好的结果,可用于实验室及工业现场的水质监测。

The design of a inspection and analysis platform of aqueous solution based on two-electrode system

A new inspection and analysis platform based on two-electrode system was constructed. The two-electrode system based on minimizing polarizing current theory was realized by maximizing the ratio of the area of working electrode and auxiliary electrode, and hardware & software were designed. Therefore the reference electrode can be abandoned, which overcomes the shortcomings of traditional three-electrode system while reproducing the function of electrochemical workstation. Research on Electric Conductivity (EC), pH and the concentrations of heavy metal ions of water had been carried out on this platform, and effective results had received which demonstrated the ability of multiple water quality parameters inspection. This platform can be used on solution properties analysis in laboratory or industry locale.
