Fundamental Studies for Development of Electrochemical COD and TOC Analyzers.

Abstract

The essential components of the Electrochemical COD and TOC Analyzers have been assembled, tested and evaluated. In situ electrochemical generation of persulfate has been demonstrated. Sensors to monitor persulfate and carbon dioxide in the analyzers have been developed and tested. The sensors have demonstrated the ability to measure chemical oxygen demand (COD) and total organic carbon (TOC) concentrations. Therefore, compact, portable, simple and relatively low cost analyzers may be developed using these components for use in field applications. An advantage is that in situ generation of persulfate in the analyzers will allow them to operate without consumables. Also, a single analyzer that can measure both COD and TOC concentrations is a demonstrated possibility. Results, conclusions and recommendations are presented. (Author)
