New biopolymer beads, composed of a Mg-Al-La tri-metal oxide (MAL) and alginate (SA), were synthesized, characterized and tested for their fluoride removal efficiency from wastewater. The morphology and properties of the beads were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). Batch sorption studies were carried out to investigate the adsorption capacity of fluoride on SA-CMAL. The equilibrium sorption data were analyzed using the adsorption isotherm models of Langmuir and Freundlich. To explore t...
