The method and apparatus for analysis of total organic carbon by using wet oxidation

摘要

The present invention relates to a method and an apparatus to measure a total organic carbon in a wet oxidation scheme, remarkably increasing oxidizing power and reproducibility to increase measurement reproducibility; and increasing oxidizing power to extend an application range. According to the present invention, the method comprises: a step of inserting a measurement sample in a reactor; a step of inserting phosphoric acid into the reactor to remove inorganic carbon; a step of inserting oxidant into the reactor to perform oxidation; and a step of analyzing carbon dioxide generated in the reactor. According to the present invention, since the method remarkably increases oxidizing power, a high measurement concentration limit is provided. Moreover, the method provides high reproducibility, thus being able to be applied to various objects such as sewage, river water, wastewater, etc.
