“…It should be pointed out that the 201 × 7 resin showed a relatively lower phosphate adsorption capacity than the modified selective resins of HFeO-IRA-400, HZrO-IRA-400, HCuO-IRA-400 [45], FVA fibrous anion exchanger resin [46], and DOW-HFO resin [14], but it was higher than that of the commercial resins of HAIX [26,44], Duolite A-7 [13], D201 × 4, D296, D301R [33], and Purolite A500P [47] resin. In addition, the adsorption of nitrate on the 201 × 7 resin led to similar results with a comparable adsorption capacity of 161.4 mg/g on Amberlite IRA 400 resin [48]. A summary of previously published literatures with the latest important results on the adsorption properties of some resins used for PO 3À 4 and NO À 3 removal were presented in Table 4.…”

2014): Co-removal of phosphorus and nitrogen with commercial 201 × 7 anion exchange resin during tertiary treatment of WWTP effluent and phosphate recovery, Desalination and Water Treatment, A B S T R A C TExcessive nitrogen and phosphorus discharge into natural water from wastewater treatment plants still have the potential of causing eutrophication. How to remove those excessive nitrogen and phosphorus in an appropriate way is welcome in practice. This study co-removed nitrate and phosphorus via the operation of commercial 201 × 7 exchange resin column, and recovered phosphate simultaneously. Experimental results demonstrated that the adsorption of PO 3À 4 -P onto the 201 × 7 resin satisfactorily fitted to Freundlich isotherm, while NO À 3 -N followed Langmuir model, with a maximum adsorption capacity of 12.47 mg/g for PO 3À 4 -P and 107.59 mg/g for NO À 3 -N, respectively. Up to 92% of PO 3À 4 -P and 90% of NO À 3 -N in the secondary effluent were recovered by 201 × 7 resin column under the optimal flow rate of 50 BV/h. The exhausted 201 × 7 resin could be regenerated by 5% NaCl within 1 h at a flow rate of 15 BV/h. Moreover, this regeneration would guarantee the effluent PO 3À 4 -P and NO À 3 -N are lower than the breakthrough points even when 1175 BV wastewater passed the resin column. These findings are of great significance for ensuring stricter effluent phosphorus and total nitrogen discharge criteria.

“…Furthermore, the calculated R L values were all in the range of 0 < R L <1, revealing that The adsorption energy E, calculated using Equation (9), according to the D-R isotherm model was used for estimating the type of adsorption mechanism. For a magnitude of E between 8 and 16 kJ/mol, the adsorption process followed the chemical ion exchange, and values of E below 8 kJ/mol were characteristic of a physical adsorption process (Chabani et al, 2009). Obtained results (Table 3) show that the E values at studied temperatures were below 8 kJ/mol, thus corresponding to physical adsorption.…”

An anion exchange membrane, (AMX) that carries a quaternary ammonium functional group has been investigated for its adsorption of fluoride, nitrate and sulfate from aqueous solutions. Fitting of the Freundlich, Langmuir, and Dubinin-Radushkevich adsorption models to the equilibrium data was performed at different temperatures in the range of 283313K. The sorption parameters of the studied models were determined by linear regression and discussed. Adsorption analysis results obtained at various temperatures showed that the adsorption pattern on the membrane followed Langmuir isotherms. Thermodynamic studies revealed that the adsorption of the AMX membrane to the studied ions was spontaneous. The 0 T G  values suggested the affinity order of the membrane for the studied anions. At 283K and 298K, the affinity order was:. This order was:

The sorption of from aqueous solution on AFN membrane has been studied and the equilibrium isotherms determined. The experimental data have been analyzed using the Langmuir, Freundlich, Temkin and Dubinin-Radushkevich isotherm models at different temperatures varying from 283 to 313 K. The results were analyzed using three kinetic models, Lagergen first order, second order and the Elovich model. The obtained results show that the best-fit correlation of the experimental data was obtained using the second order model. Thermodynamic parameters for the adsorption system were determined at 283, 298 and 313 K.
