Abstract
A set of heavy metal online detection system was developed for water based on electrochemical stripping voltammetry, in the process of development, some intelligent function modules were introduced, such as system health-checking, variable-error automatic compensation and automatic rang switching function, improved the accuracy and intelligent level of the monitoring systems. Under certain experimental conditions, through standard solution testing experiment of Zn, Pb, Cd and Cu ions, results show that the novel system can effectively solve the serious influence from the environment in field work and eliminate error automatically in multi-element mixture detection, which the traditional detection system can't solve. Experiments demonstrate that the novel intelligent designs improved the detection precision, reliability and adaptability of the system obviously, for online monitoring and unattended occasions, it will be more effective.
