ON-LINE ANALYSIS SYSTEM FOR HEAVY METAL USING AN ELECTROCHEMICAL ANALYSIS METHOD

摘要

Provided is an on-line analysis system for heavy metal using an electrochemical analysis method capable of reducing generation of environmental contamination materials and improving surface stability and reproducibility. The on-line analysis system includes a working electrode for measuring the type and concentration of heavy metal by applying a voltage for a certain time to enrich heavy metal ions existing in a sample solution, and gradually applying an opposite voltage to strip an enriched material to thereby measure current, characterized in that the working electrode is formed of an enriched metal electrode in which a metal solution is adsorbed onto a bottom electrode to form an electrode film.
