Desorption of humic acids from an iron oxide surface

Article Abstract:

The absorption of humic acids on iron oxide-coated silicon plates were shown to be dependent on pH, with a decrease in pH increasing humic acid absorption. Desorption was achieved either through a change in pH with no corresponding change in the concentration of the humic acid or upon dilution with no corresponding change in pH. Desorption using the change in pH was found to be reversible, with additional increases in pH accelerating the desorption process.

Dialysis investigations of atrazine-organic matter interactions and the role of a divalent metal

Article Abstract:

Results of dialysis investigations of surface and groundwaters to determine atrazine retention indicated that initial concentration do not affect atrazine retention. Natural organic matter (NOM) appeared to aid atrazine retention in membranes with molecular mass cut-offs less than 500 Da by transitory hydrogen bonding and subsequent physical entrapment. Atrazine retention, however, is observed to decrease at higher ionic strengths.
