Abstract
This study demonstrates the synthesis and characterisation of core–shell particles for the removal of chlorides from water. The evaluation of their efficiency was conducted under a variety of experimental conditions. The core–shell particles consist of an organic template coated with Mg–Al–NO3 layered double hydroxides (LDH). The characterisation of the LDH traps in terms of their morphology, structure and composition was accomplished with a variety of techniques such as SEM, energy dispersive X-ray analysis, Fourier transform infrared spectroscopy, X-ray diffraction, and thermogravimetric analysis. The LDH trap chloride adsorption loading was evaluated in respect of several parameters such as temperature, pH, contact time and dosage of traps. The experimental data fitting on kinetics models indicated that the adsorption's rate determining step was the chemisorption mechanism.
