Measure of chemical oxygen demand by an inexpensive electrochemical instrument

Abstract:

This article describes the implementation of an inexpensive electrochemical instrument and its performance when it is used to measure the chemical oxygen demand (COD). Low cost precision electronic devices and electrochemical system were used to build it. Homemade copper electrode let made COD measurements in synthetic wastewater. Excellent results were achieved against conventional method for COD measurement.
