摘要

Abstract

The application of cross-flow ultrafiltration (CFF) techniques to separate colloidal organic carbon (COC) from truly dissolved organic carbon(TDOC) was investigated; COC and TDOC were determined by the high-temperature combustion method(HTC) and UV/persulphate method. It was found that CFF can quantitatively separate COC from seawater. The determination results by the HTC and UV/persulphate method for COC and TDOC showed little difference

which suggested that the oxidation efficiency of the two methods are identical. Colloidal particles have no remarkable influence on the oxidation efficiency of the UV/persulphate method.
