  Abstract

ed and the effects of contact time, pH, and initial concentration of (bovine serum albumin) BSA on its adsorption by TICR were investigated. The Langmuir isotherm model was applied to describe the adsorption isotherm. The equilibrium data are fitted to the Langmuir isotherm model. The maximum monolayer BSA adsorption capacities of TICR were found to be 1.094, 1.487, and 1.694 mg/g at 298, 308, and 318 K, respectively. Furthermore, the data were analyzed on the basis of pseudo-first order, pseudo-second order, and intraparticle diffusion models. The correlation results suggested that the pseudo-second order model fitted the experimental data very well. The thermodynamic study indicated that the adsorption process of BSA onto TICR was endothermic, and the Gibbs free energy (Go), enthalpy (Ho), and entropy (So) of the adsorption process were calculated according adsorption isotherm data. TICR could be reused for 10 times with only 19 % loss of adsorption capacity for BSA.
