Application of photoelectrochemical chemical oxygen demand to drinking water
This study investigated the use of a photoelectrochemical chemical oxygen demand (peCOD) analyzer for the detection of model organic compounds and natural organic matter (NOM) from four drinking water treatment plants in Nova Scotia, Canada. Most model organic compounds showed reasonable correlation between peCOD and theoretical oxygen demand (ThOD), indicating that peCOD was a reasonable predictor of chemical oxygen demand (COD). Results also showed that peCOD/TOC (total organic carbon) ratios followed predicted values from stoichiometry, when peCOD was a good predictor of ThOD. peCOD determination for surface water showed that peCOD was measurable in the raw and treated drinking water range and trended with other organic matter surrogates. Finally, pooling of raw water, finished drinking water, and water sampled throughout the treatment process at these four utilities showed that peCOD was correlated with specific ultraviolet absorbance at 254 nm (SUVA).
