Abstract

Water pollution is a major problem all over the world, the detection techniques of water play an important role in the evaluation of water pollution. Chemical Oxygen Demand (COD) is an important index of the evaluation of water pollution. The paper reviews the detection methods of chemical oxygen demand in wastewater, introduces the standard of chemical oxygen demand emission limit in different countries, the traditional detection methods and their optimization, the new detection techniques which include chemiluminescence, spectrometry, electrode, microbial fuel cells, silver nanoparticles sensor and so on. It’s important to establish a new environmentally friendly chemical oxygen demand detection method with safe and high efficiency in the further.
