THE COMPARATIVE DETERMINATION OF THE DISS OLVED ORGANIC-MATTER IN DIFFERENT SEAS BY THE WET COMBUSTION AND THE HIGH-TEMPERATURE CATALYTIC-OXIDATION

The paper presents a comparison of the completeness of organic carbon oxidation by the two methods, the photochemical; oxidation with potass ium persulfate and the high temperature catalytic oxidation (HTCO), at measurements in organic compounds of various element composition and complexity. The data on estimations of dissolved organic carbon (DOG) by the two methods in the waters of the Black, Bering, and Okhotsk sea s are presented. The different degree of oxidation is shown to depend on the region and depth. It is concluded that the HTCO is more prefera ble for DOC determination, as it is easier to standardize, whitle the values obtained by the method of wet oxidation are influenced by a lot of hardly accountable factors.
