Abstract

Abstract

The application of cross-flow ultrafiltration (CFF) techniques to separate colloidal organic carbon (COC) from truly dissoloved organic carbon (UOC) has been investigated, and both COC and UOC were determined by high temperature combustion method (HTC) and UV/persulphate method. It was found that CFF can separate COC from sea water quantitatively. The determination results by the HTC and UV/persulphate method for COC and UOC showed little difference, which suggested that the oxidation efficiency of the two methods is identical. Colloidal particles have not remarkable influence on the oxidation efficiency of UV/persulphate method.
