Abstract:The size exclusion chromatograms of humic acid(HA) and fulvic acid(FA) were studied by using column packed with controlled-pore glass(CPG), and with water or aqueous salt solution as eluents. The experiment shows that an unusual exclusion phenomenon was verified to be the coulombic repulsive force induced by CPG and HA or FA. This unusual exclusion could be inhibited by using aqueous salt solution as eluent, and the concentration of salts in the eluent has a marked effect on the elution chromatograms. The influence of the concentration of added salt on the size exclusion chromatograms of polyelectrolyte was discussed.
Keywords:Humic acid   Fulvic acid   Contrclled-pore glass stationary phase   Size exclusion chromatography
