A Comparative Study on the Evaluation of BOD Analysis Methods

Abstract

In this study, data for increasing the efficiency of researcher manpower and establishing the validity of the electrode method are presented via a comparative evaluation of the titrimetric and electrode methods for BOD analysis. When comparing the analysis results of the titrimetric and electrode methods for wastewater, sewage, and leachate, no difference was observed between two methods. Therefore, if the electrode method is used instead of the titrimetric method, the amount of reagents for BOD analysis can be effectively reduced, resulting in a decreaded workloads for analysts as well as the hazards and risks posed to them, ultimately. In addition, the amount of acid wastes generated due to the use of sulfuric acid can be reduced, thereby reducing costs, which is economically beneficial.
