Abstract

A rapid BOD measurement system using a microbial membrane electrode has been developed. Culture of microorganism and the preparation of microbial membrane, the effect of sample flow rate on the BOD measurement, the effect of solution pH and response characteristics of the microbial membrane electrode were investigated. The rapid BOD measurement system developed by us was connected to a personal computer and the whole BOD measurement procedures were carried out automatically. The best results were obtained when the solution flow rate was 7.8mL/min and the data were obtained 5 minutes after sample injection.
