Study on Online Detection Device for Heavy Metals in Water Environment

This thesis has developed a set of low detection and analysis device for heavy metal detection. The online detection device of the low cost heavy metal on-line detection device is based on the electrochemical stripping voltammetry and uses the three electrode system as the sensor unit. The stability and accuracy of the system were significantly improved by using multiple regression temperature compensation, and the real-time and accurate detection of the interrupt equipment was realized. The device has the advantages of low cost, small volume and easy to carry, and achieve better stability and accuracy.
