A study was made of the adsorption of humic substances (HS) by Mn 3 O 4 and by oxide B, a preparation with the -MnOOH diffraction pattern but having a manganese oxidation state of 3.4. The interactions follow trends found for other oxides. Thus in 0.01 mol dm -3 NaCl adsorption decreases with increasing pH, while it is enhanced by Ca 2+ . The HS adsorb more strongly to the oxide with the higher zero point of charge (Mn 3 O 4 ), while the effect of Ca 2+ is greater for oxide B. Microelectrophoretic measurements show that the oxide particles take on the electrokinetic characteristics of the adsorbed HS. However it was found that the magnitude of the mobility depends on the underlying oxide surface and on the source of the HS. The electrokinetic properties of the two oxides dispersed in surface water samples of Esthwaite Water, Cumbria, England, can be accounted for by the adsorbed HS together with coadsorbed Ca 2+ .
