A method based on all band ultraviolet scanning for measuring water chemical oxygen demand (COD) was introduced, and the method was applied to develop an on-line COD measuring instrument.
According to the study agriculture is responsible for 43.7% of the nation's chemical oxygen demand (the main measure of organic compounds in water) 67% of phosphorus and 57% of nitrogen discharges.
