Point of zero charge (PZC) is one the most valuable parameter of adsorbent preparation process, in
wastewater management. Although, this parameter may be determined measuring the electrokinetic potential (zetta
potential) as the function of pH; material engineers oftenrely on pH PZC value which may be easily determined and
can give usefuladsorbent properties duringexploitation. Samples from previous study are characterized and their pH
PZC values are determined. Provided results are such intriguing since they brought conclusions that those values can
be explained by process parameters of the particular sample preparation. Sample marked as Cr2O3/Fe3O4/EVer have
lowest pH PZC value (4.75) and sample marked as MnFe2O4/EVer highest pH PZC value (7.47). Another study in this
paper showed that pH PZC value could be easily increased or decreased by simple base or acid treatment, respectfully.
As expected, samples treated with bases or prepared in alkali medium have greater adsorption ...capacity towards
cation species, up to 20 % more than base material in the case MnFe2O4/EVer.
