- Abstract
- The factors affecting iron(III) adsorption by strongly acidic Dowex G-26(H) cation-exchange resin are studied. These factors include the adsorbent dose, pH of the solution, contact time, initial Fe(III) concentration in the solution, and temperature. Langmuir and Freundlich adsorption isotherms are constructed from the experimental results. Both isotherms quite satisfactorily describe Fe(III) adsorption by the Dowex G-26(H) adsorbent, which is indicated by high (close to unity) coefficients of determination (R2). The calculated capacity of the adsorbent ranges from 166.6 to 196.1 mg g–1 at different temperatures (T = 293–313 K). The kinetic and thermodynamic parameters of the process (ΔH°, ΔS°, ΔG°) have been determined. The positive calculated standard entropy (ΔS°) and enthalpy (ΔH°) changes suggest that the adsorption of Fe(III) ions on the resin is endothermic and spontaneous.
