Method of measurement:
ECO-Sensing COD-EC500 Analyzer is a chemical oxygen demand (COD) sensor employing a stopped-flow thin layer electrochemical cell. The coulometric charge required for exhaustive electrolysis of samples was measured and correlated with the COD evaluated by the standard COD laboratory method. A single measurement took about 15 minutes, much less than the two hours required in the conventional method. Linear sweep voltammetry was performed using both real samples and standard compounds.
