More Information
Summary:Procedures for studying the organic matter dissolved in marine pore waters were considered. The fractionation of natural dissolved organic matter (DOM) was conducted more efficiently than in conventional procedures by coupling tangential ultrafiltration and gel permeation chromatography, with sea water as the eluent, prior to further general DOM characterization. The proposed method simplified DOM characterization without the need for extraction, chemical treatment or preconcentration on a resin. It also facilitated investigations which were difficult to carry out directly. An example concerning the ability of pore water fractions to form copper complexes is cited.
