Batch Adsorption Process Composite Material Cr(VI) Fly Ash (FA)
2011/11/22
The adsorption technique using fly ash composite material has been applied for the removal of Cr(VI) from aqueous samples. Batch experiments have been carried out for the adsorption of Cr(VI) onto fly...
Influence of Fe(II) on the Formation of the Spinel Iron Oxide in Alkaline Medium
Dissolution Ferrihydrite Maghemite Magnetite Mossbauer spectroscopy
2011/12/31
Fe(II) and Fe(III) in various proportions were coprecipitated by NH3 at pH ≈ 11. The Fe(II)/Fe(III) ratio (x) was varied from 0.10 to 0.50. After stabilization by aging at pH ≃ 8 in anaerobic co...
Adsorption of Alkylphosphoric Acid on Kaolinite and Smectite in an Organic Medium (Decane)
Adsorption Alkylphosphoric acid Hectorite Infrared spectroscopy Kaolinite Smectite Surface reactions
2012/2/8
Di-ethyl 2-hexylphosphoric acid (di-2 EHPA) was chemisorbed on kaolinite and smectite in decane solution. The resultant isotherms were of the Langmuir type and made possible the determination of limit...
Acetamide and Polyacrylamide Adsorption onto Clays: Influence of the Exchangeable Cation and the Salinity of the Medium
Acetamide Adsorption Montmorillonite Polyacrylamide Saline Media
2012/2/10
The adsorption of acetamide and partly hydrolyzed polyacrylamides onto montmorillonite has been investigated with emphasis on the valency of the exchangeable cation of the clay and the ionic strength ...
