DETERMINATION OF DISSOLVED ORGANIC CARBON IN SEAWATER

Abstract:

This article presents an improved method for the determination of dissolved organic carbon (DOC) in seawater with an infrared CO₂ gas analyzer as proposed by Menzel and Vaccaro^[60]. Within the concentration range of DOC from 0.5 to 4 mgC/L, the relative standard deviation, the recovery, blank and the lowest limit of the determination are <5%, >97%, 0.1 mgC/L and 0.05 mgC/L, respectively. At least 20 samples can be analyzed in an hour with this method.
