Zeta Potentials of Metal Oxides Coated with Titanate Coupling Agents in Aqueous Solution

Removal of Fe2+ from Aqueous Solution Using Manganese Oxide Coated Zeolite and Iron Oxide Coated Zeolite

The adsorption of Fe2+ by the manganese oxide coated zeolite (MOCZ) and iron oxide coated zeolite (FOCZ) was studied. Surface properties of adsorbents have been investigated for monitoring their changes and morphology for both of the MOCZ and FOCZ. Main variables namely; contact time, pH, initial concentration of Fe2+, size and dosage of adsorbent have been optimized, and the results contrasted...

Aqueous Atrazine Removal by Activated Carbon / Metal Oxides Composites

In this work the removal of atrazine herbicide from aqueous medium was investigated using different catalysts based on activated carbon impregnated iron or chromium oxides. The materials were characterized by powder XRD, scanning electron microscopy (SEM) and infrared spectroscopy (FTIR). The characterization showed the formation of small particle size goethite (α-FeOOH) phase on activated carb...

The Synthesis of Nano-Crystalline Metal Oxides by Solution Method

Thermodynamic and kinetic properties of metal ions in aqueous solution

While it is evident that a metal ion in aqueous solution interacts electrostatically with water molecules and the anions present in the solution, it is equally apparent that often the metal ion chemically combines with varying numbers of ions or molecules to form complex species. This tendency towards coordination complexing is observed most often with the transition metals and results in a ser...
