Nanostructured composite sorbent of Mg/Al-aminobenzoate layered double hydroxide was prepared by coprecipitation method.
The particle size of the nanocomposite was found to be 10-20 nm.
Sorption performance of the prepared material was studied for removal of cobalt ion from aqueous solution.
The percent uptake of cobalt ion was found to be 96.1%.
The loading capacity of Mg/Al-aminobenzoate composite for Co2+ ion was studied and found to be 5.2 meq/g.
From the kinetic studies, the results illustrated that the mechanism of the sorption process was controlled by pseudo-second order model.
The sorption process was chemisorptions since the value of diffusion coefficient is in the order 10-17 m2/s, as well as the good fit of Elovich model.
The sorption was controlled by intra-particle diffusion mechanism.
From isotherm investigations, it was found that Langmuir model fitted the results better than Freundlich model.
Stripping process was carried out, the results illustrated that cobalt ion can be completely stripped with 3 M HNO3.
A comparison of the sorption capacity of the prepared material with other sorbents reported in the literature was investigated and indicated that the prepared nanocomposite has much higher sorption capacity than many other sorbents.
The whole results indicated that Mg/Al-aminobenzoate nanocomposite is an efficient sorbent and recommended for removal of Co2+ ions in a wide range of concentrations.
