Abstract
The correlation between ultraviolet absorbance at 254 micrometer (A(254 micrometer)) and total organic carbon (TOC) content has been determined for a variety of treated and untreated water samples. These samples ranged from municipal secondary sewage effluent and river water to municipal tap water. High correlation coefficients were obtained for water samples which contained sufficient organic carbon to permit accurate TOC determinations. Predictably, systems with low TOC levels yielded lower correlation coefficients. However, even with the lower correlation coefficients, absorbance measurements can still be used to monitor a process stream for its organic carbon content if interferences from turbidity do not exceed certain limits.
