Preparative HPSEC using DI water as mobile phase effectively reduced heterogeneity of DOM. Negligible DOC loss (recovery > 97%) observed after preparative HPSEC. Structural alteration of DOM after preparative HPSEC was not significant. Biopolymer composition played a key role in complexation of DOM with inorganic species.
