A B S T R A C TIn this study, the sorption ability of nitrate containing MgAl layered double hydroxide as an anion-exchanger to remove phosphate from a real effluent was investigated. The LDH material was prepared via coprecipitation method and characterized by X-ray diffraction, SEM, Fourier Transform Infrared, BET surface area, and pH zpc . The effect of physico-chemical key parameters on phosphate removal, such as sorbent dosage, solution pH, initial concentration, and contact time, has been studied in batch mode. The sorption reached equilibrium within 30 min. Furthermore, the sorption mechanism of phosphate onto MgAl-NO 3 LDH is a combination of both anion-exchange and electrostatic attraction. The equilibrium 8 data were tested using Langmuir, Freundlich, and Dubinin-Radushkevich isotherms. The results show that the Langmuir isotherm describes sufficiently the sorption equilibrium, offering a maximum sorption capacity of 64.10 mg/g. Sorption kinetic follows accurately pseudo-secondorder reaction. The sorbent reusability shows that regenerated LDH can be reused in subsequent sorption-regeneration cycles with a slight decrease in sorption capacity.

“…Based on previously published studies, the effect of pH on the removal of aluminum and iron ions by RHAC was studied in the range between pH 2 and 5 to avoid metal ions hydroxide precipitation at higher pH values [20] and [21]. Figure 3 represents the removal percentage of aluminium and iron ions at different initial pH values.…”

The adsorption of aluminium(III) and iron(III) ions from their single and binary systems, by RHAC was investigated in a batch system. The activated carbon prepared from rice hulls was characterized by scanning electron microscopy and Fourier transformation infrared techniques. Batch adsorption experiments were performed under different operating conditions including pH (2 -5), adsorbent dosage (0.5 -2.0 g/l), initial ion concentration (5 -100 mg/l), and contact time (30 -240 min). The equilibrium time for maximum ions removal was found to be 180 min in single and binary ions systems. The kinetics of adsorption was evaluated using the pseudo-first order, pseudosecond order and Elovich kinetic models. The Langmuir, Freundlich and Temkin equilibrium models were applied to the adsorption experimental data. Real wastewater samples were collected from different locations to investigate the efficiency of rice hull activated carbon in treating real samples. The real wastewater samples were treated with the activated carbon prepared from rice hulls and a commercial activated carbon. The results showed that the activated carbon prepared in the present work was more efficient in the removal of aluminium and iron from real wastewater as compared to the commercial activated carbon which is more advantageous considering both economics and environmental parameters.

“…If this value is between 8 and 16 kJ/mol, the adsorption process can be assumed to involve chemical adsorption. On the other hand, values lower than 8 kJ mol −1 indicate that the adsorption process is of a physical nature [32][33][34].…”
