A method based on all band ultraviolet scanning for measuring water chemicaloxygendemand (COD) was introduced, and the method was applied to develop an on-line COD measuring instrument.
To rapidly determine the pollution extent of wastewater, the potential of near infrared(NIR) spectroscopy for measurement of chemicaloxygendemand(COD) in wastewater was investigated.
