Abstract
In analysis of total organic carborn (TOC), efficiency of organic oxidation is critical. There are two most well-known methods to oxidize TOC in the analysis. They are the thermo-oxidation method, and the UV-persulfate oxidation. In the thermo-oxidation method, organics in water samples is thermally oxidized to CO2 which is sequentially analyzed. In the UV-persulfate oxidation, organic material in water samples is photo-oxidized in the presence of persulfate. In this study, oxidation efficiencies of these two different methods for TOC quantification were compared by applying them to a number of water samples; some of them contained easily degradable organic carbon and some of them did hardly-degradable organic carbons. As a result, the TOC values quantified by the UV-persulfate method were about 10-20% smaller than those quantified by the thermooxidation method. When the water samples with large amount of organics were analyzed for TOC, the difference became larger.
