COD On-Line Monitoring Based on Photometric

Abstract:

The chemical oxygen demand (COD) is an important indicator of the characterization of organic substances in water content, reflecting the situation of water pollution. This system takes the IC, A/D and AT89C52 as key module, according to Lambert-Bill’s law and colorimetric principle, uses silicon photovoltaic cells and operational amplifier to realize photoelectric conversion. Incident light and transmitted light intensity of liquid are measured. The microcontroller can be automatically calculated the solution of the chemical oxygen demand (COD) value. The system also has real-time clock, over-range alarm and other functions.
