摘要

Abstract

A comparison between the high-temperature catalytic oxidation method (HTCO) and the UV/persulphate method for the determination of dissolved organic carbon (DOC) in seawater is presented in this paper. In seawater sample chloride ion can affect the oxidation efficiency of the UV/persulphate method if the asymptotic concentration of persulphate is not reached. During HTCO analysis

blanks that appear to originate mainly from the catalyst are high and far from constant. If the blanks are well estimated and correction is made

the difference of determined DOC values between the UV/persulphate method and the HTCO method is small

the HTCO values being slightly higher.
