| Abstract: | The present invention provides mixed metal oxide-hydroxide biopolymer composite beads for fluoride removal from groundwater and a process for the preparation thereof. The beads developed in the instant invention relate to novel granular adsorption medium which comprises two or more metal oxide-hydroxide/hydroxide/oxide nanoparticles and calcium alginate as supporting medium. The said mixed metal oxide-hydroxides and biopolymer composite (MBC) beads are useful for the treatment of fluoride containing drinking water by both batch and continuous mode operations. The MBC beads also showed arsenic sorption performance from spiked water by batch mode. |
