Abstract

in this paper, the sorption activity of Salvadora persica fine particles provided from internal natural resources in Iran with respect to Crystal Violet, Basic Violet-16 and Basic Blue-41 dyes is investigated. Salvadora persica particles were modified and prepared via particle size reduction and they were characterized by CHNS, XRD, SEM and FT-IR analysis. In the batch system, the influence of pH, adsorbent dosages and dye initial concentration was investigated. The results of isotherm and kinetics studies show that the Langmuir isotherm and pseudo-second order kinetic have better correlation with the experimental data. Calculations of thermodynamic parameters show negative Gibbs free energy (Δ G) values or spontaneous reaction, the enthalpy (Δ H) changes shows the exothermic process and values of entropy (Δ S) indicate low randomness at the solid/solution interface during the uptake of dyes. So, these locally available cheap adsorbents for the removal of Basic dyes from the aqueous solution have high efficiency and can also be utilized for other water pollutants such as toxic elements.
