Performance of Strong Acid Cation Resin D072 for the Adsorption of Fe (II) from Aqueous Phase

Resin D072 was more useful on the adsorption of Fe2+ as a heterogeneous catalyst in the presence of H2O2, which had high catalytic activity in the decolorization of reactive red KE-3B. The conditions of the adsorption of Fe2+ by D072 were optimized, including the initial pH, the Fe2+ concentration and reaction time. It was found that the optimal pH was pH3. The optimal initial concentration of Fe2+ and reaction time were 840 mg L-1 and 60 min, respectively. It illustrated that the adsorption behavior of Fe2+ by D072 obeyed Freundlich adsorption model. The decolorization reaction of reactive red KE-3B was still faster though the catalyst already used 10 times because Fe leaching from the catalyst was negligible. The heterogeneous catalyst seems to be viable method for achieving significant decolorization of dying industry wastewater.

Separation Results

In the research work, the adsorption equilibrium, kinetics, thermodynamics and dynamic separation of magnesium and calcium ions from industrial wastewater by new strong acid cation resin of SPVC (sulphonated polyvinylchloride) were investigated. The sorption capacity of the studied resin was 3.78 mmol/g and 3.74 mmol/g for magnesium and calcium ions, respectively, according to Langmuir isotherm. It was found that the pseudo−first−order model was better fitted for the adsorption kinetics of magnesium and calcium ions on the resin. The dynamic separation results confirmed that the selected resin effectively separated magnesium and calcium ions from industrial wastewater in the dynamic condition. The change of the standard Gibbs free energy (G) and enthalpy (H), and entropy (S) were calculated. The obtained results confirmed that the adsorption of magnesium and calcium ions on the selected resin is endothermic.

Initial Ph

A mesoporous SBA-15 doped iron oxide (Fe2O3/SBA-15) was synthesized by co-codensation, characterized and used as heterogeneous catalysts for the photo-Fenton decolorization of azo dye Orange II under UV irradiation. Response surface methodology (RSM) was used to investigate operating condition effects, such as hydrogen peroxide concentration, initial pH and catalyst loadings, on the decolorization rate. UV irradiation is found to enhance the activity of the catalyst in the process. RSM analysis evidenced the influence of the initial pH value and H2O2 concentration on the dye degradation rate. The coupled UV/Fe2O3/SBA-15/H2O2 process at room temperature is revealed as a promising friendly process for wastewater treatment. Indeed, the use of a heterogeneous catalyst allows an easy active phase recycling without multi-step recovering while the heterogeneous catalyst used here exhibits high catalytic activity for the reaction considered.
