EXTRANEOUS DIFFUSION KINETICS OF AMMONIUM IONS ADSORPTION IN THE PRESENCE OF OTHER IONS

نویسندگان

چکیده

The article presents the results of study kinetics ions adsorption from multi-component mixtures. isotherms sorption ammonium nitrogen in presence phosphates indicate a decrease exchange capacity zeolite due to its competition for active absorption centres. This was carried out with two inorganic nature. In third organic component solution (protein substance - albumin), decreases even more comparison ions. It found that phosphates, equilibrium towards by about 30%; three-component system reduction reaches 70%.

Adsorption of Ni2+ Ions onto NaX and NaY Zeolites: Equilibrium, Kinetics, Intra Crystalline Diffusion, and Thermodynamic Studies

This paper focuses on intra crystalline diffusion of Ni2+ ions onto NaX and NaY zeolites. The zeolites are obtained by the hydrothermal synthesis method. The samples were characterized by several techniques: X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) coupled with Energy Dispersive Spectroscopy (EDS) and InfraRed Spectroscopy (FT-IR). Physical parameters such as p...

Removal of copper (II) from aqueous solutions by adsorption onto granular activated carbon in the presence of competitor ions

In this work, the removal of copper from an aqueous solution by granular activated carbon (GAC) in the presence of competitor ions was studied. A batch adsorption was carried out and different parameters such as pH, contact time, initial copper concentration and competitor ions concentration were changed to determine the optimum conditions for adsorption. The optimum pH required for maximum ads...

Experimental modeling of the adsorption kinetics of Cd (II) and Pb (II) ions by Calix [4] arene surface

The removal of Cd2+ and Pb2+ ions from wastewater using p-tert-butyl-calix[4] arene was investigated in terms of initial pH, initial concentration, adsorbent dosage, contact time and temperature. The maximum adsorption occurred at the pH value of 6. The adsorbent studied exhibits high efficiency for Cd (II)and Pb (II) adsorption and the equilibrium states could be achieved in 10 min. Adsorption...
