Using the batch technique, sorption of As(III) ion by SiO2-Cys was studied, and the effects of pH, sorbent dosage, temperature, initial concentration, and contact time were all taken into consideration. According to kinetic studies, the pseudo-second-order equation adequately described the sorption of the As(III) ion. The spontaneity of the sorption process on SiO2-Cys is suggested by the negative values of Gibbs free energy (G°). Positive values of enthalpy (ΔH°) indicate the endothermic adsorption process and the positive values of entropy (ΔS°) for As(III) ions adsorption imply that the adsorption involves increasing randomness.
