✦ Synopsis

adsorption and coprecipitation. Changes to the sign of the The adsorption and coprecipitation characteristics of Cr(III), zeta potential (charge reversal), for example, are directly Zn(II), and Ni(II) with amorphous hydrous iron(III) oxide related to sudden changes in adsorption density (3, 4). (HFO) and those of Zn(II) and Ni(II) with amorphous hydrous James and Parks (5) have reviewed electrical double layer chromium(III) oxide (HCO) have been measured by the authors models for their suitability in estimating surface charges and
