摘要： A method of determining chemical oxygen demand in water samples containing chloride ions above 0.5mM concentration in which the samples are diluted and a known quantity of an organic substance is added to the diluted sample which is the subjected to an assay by a photoelectrochemical method using a titanium dioxide nanoparticulate semiconductor electrode and measuring the photo current produced until a stable value is reached and then using the difference between the initial and stable photocurrents as a measure of the chemical oxygen demand. An alternative method involves determining chemical oxygen demand in water samples containing chloride ions by measuring the chlorine content and measuring chemical oxygen demand by a photoelectrochemical method using a titanium dioxide nanoparticulate semiconductor electrode and adjusting the chemical oxygen demand measurement using the chlorine measurement.
