Paper Abstract

The chemical oxygen demand(COD) in Seawater is an organic contaminant synthetical indicator and one of the most important ocean environment monitoring items. At present, the marine pollution in China is serious day by day, but the traditional COD measurement method can not meet demand. It is essential to research the real-time monitoring system with no time delay, no reagent application and no secondary pollution. The basic principles of analytical techniques and a real-time monitoring system for the measurement of seawater COD were described in this paper. The basic principles were based on the ultraviolet absorbency degree analytical method. The correlation between ultraviolet absorbency degree and COD in seawater was studied in this paper. The result showed that under certain condition, it could calculate COD value from ultraviolet absorbency degree. A novel seawater COD sensor was designed in this paper, and it could circularly lead in the seawater cleaning out the contamination.
