Abstract

A sensor to determine TOC is described. It is based on the photoassisted degradation of organic compounds concurring to TOC and on the determination of the resultant CO2. The sensor was successfully tested on target molecules, demonstrating that the linear correlation constant between TOC values and produced CO2 varies according to the considered compound so that absolute value determination is not possible in largely heterogeneous solutions but can only be referred to reference compounds on the TOC scale.
