Using the UV sodium persulfate oxidation method, one sample is subjected to catalytic oxidation reaction with acid added persulfate solution under UV light to produce CO2, while the other sample is acidified with an acid reagent to produce CO2; The generated CO2 is transported to a non dispersive infrared gas detector through high-purity nitrogen as a carrier gas, resulting in total carbon (TC) and total inorganic carbon (TIC), respectively. The difference between the two is the total organic carbon.

1. Adopting oxidant and UV oxidation technology. "
