Abstract
Disclosed herein is an electrochemical measurement system for analyzing heavy metals in organic compound-containing samples, comprising: a lower plate; a flow channel plate; an upper plate; an organic compound-decomposing electrode and a heavy metal analysis electrode; and a flow changeover portion. The disclosed system can continuously perform a pretreatment process for organic compound decomposition and a process for heavy metal analysis, thus making it possible to achieve the selective analysis and separation of heavy metals in wastewater. Also, it can substitute for expensive spectrophotometric analysis equipment and makes it possible to monitor trace heavy metals on-line in situ. In addition, it may include a small-sized battery as a power source, such that it is easy to carry and use.
