Evaluation of a Breadboard Electrochemical TOC/COD Analyzer.
Abstract
The Breadboard Electrochemical TOC/COD Analyzer has been assembled, tested and evaluated. The Analyzer operates on the basis of UV-catalyzed oxidation of organic solutes by persulfate. The Breadboard Analyzer has demonstrated for the first time that this technique can be used to measure COD concentrations and that COD measurements can be made simultaneously with TOC measurements using only one analyzer. Operating conditions have been optimized and synthetic and real samples have been analyzed. The results obtained with the Breadboard Analyzer agree closely with the results of standard methods. Particulates do not interfere in the analyses and samples ranging from tap water to raw sewage have been successfully analyzed. The Breadboard Analyzer has been designed using concepts and analysis techniques that lend themselves to accurate, automated operation in the field and in industrial process monitoring and control applications. Future developments are anticipated to lead to automated, unattended operation for at least 30 days. Results, conclusions and recommendations are included. (Author)
