Abstract :Chromium insert ignore into journalissuearticles values(VI); batch system sorption from aqueous solutions by use of commercial Eichrom 1x4 anion exchange resin was studied at varying pH, temperature, and contact time, adsorbent dosage, desorption study, and starting Cr insert ignore into journalissuearticles values(VI); concentration. The ideal pH range for Cr insert ignore into journalissuearticles values(VI); sorption via anion exchange resin insert ignore into journalissuearticles values(AER); was found as 2.0-6.0. The kinetic of Cr insert ignore into journalissuearticles values(VI); sorption by resin came after the secondorder kinetic model. The greatest chromium sorption emerged at 10 min for AER. The sorption isotherms were investigated with Langmuir, Freundlich and Redlich-Peterson models. The optimum isothermal model for chromium sorption via AER was the Langmuir isotherm. Moreover, the sorption thermodynamic parameters like entropy change insert ignore into journalissuearticles values(ΔSo);, free energy change insert ignore into journalissuearticles values(ΔGo);, and enthalpy change insert ignore into journalissuearticles values(ΔHo); were also investigated. A rise in the temperature has resulted in a rise of the equilibrium constant insert ignore into journalissuearticles values(Kc); value for the Cr insert ignore into journalissuearticles values(VI); sorption by AER.
