Chromatographic Fractionation of the Hydrous Oxide Ions
Chromatography is the name given to a technique for the analysis of mixtures by passage of their solutions through an adsorbent column. The different constituents adsorb at different rates, and advantage is taken of this property to separate the components into different sections of the column. …

SYNTHESIS AND CHARACTERIZATION OF MODEL AQUATIC PARTICULATES FOR USE IN SORPTION STUDIES
… fulvic acids, and iron, aluminum, and manganese hydrous oxides. Characterization included measurement of cation exchange capacity (CEC), and attempts to determine surface area and the pH of zero point of charge. Each of these methods was tested to determine their applicability to aquatic …

Sorption of lead and arsenic on soil components and effectiveness of phosphates for remediating lead and arsenic contaminated soils
… undertaken to evaluate the effect of Fe and Al hydrous oxide coatings on the sorption of Pb and As. Four clay minerals attapulgite, illite, kaolinite and montmorillonite with a range of surface characteristics were selected to investigate the Pb and As sorption. The minerals were coated with …

The colloid and surface chemistry of allophane
… charged at near neutral pH, and aluminium hydroxide which tends to bear a positive charge under the same conditions. Dissolution studies showed that allophane derived from Tirau soil had aluminium in a state similar to that in aluminium hydroxide gel; that from Ohaupo soil had aluminium in a …
