Adsorption of some albumins on charcoal derived from oleasterseed

The In recent years many researchers has been focused on the use of biomass residues as low cost and locally available adsorbents for the removal of different organic and inorganic chemicals by the adsorption process. In this study the powder of Oleaster Seed were used in their charcoal form for the removal of Bovine serum Albumin (BSA)and Egg white Albumin(EWA)from aqueous solution. Various experimental parameters such as BSA and EWA concentrations, contact time, adsorbent dose, pH and temperature were studied to establish the conditions for the removal of BSA and EWA. Isotherm data were fitted to the Langmuir and Freundlich adsorption isotherm equations. Results showed that the maximum extent of adsorption occurs in pH=5 and pH=3 at a temperature of 302K for Oleaster Seed charcoal respectively. Thermodynamic data ΔG, ΔH and ΔS showed that the adsorption process is exothermic on the surface of Oleaster Seed.
