Analysis of equilibrium, kinetic, and thermodynamic parameters for biosorption of fluoride from water onto coconut (Cocos nucifera Linn.) root developed adsorbent
Abstract Drinking water with higher fluoride levels results in serious irremediable health problems that have attained a startle all over the world. Researches focused towards deflouridation through the application of biosorbents prepared from various plants are finding greater scope and significance. Present research is done on Cocos nucifera Linn. (coconut tree) one of the very […]

Adsorption of fluoride from aqueous solution by fly ash cenospheres modified with paper mill lime mud: Experimental and modeling
Highlights A low-cost fly ash cenospheres modified with paper mill lime mud adsorbent was prepared. Response surface methodology was employed to research the effects on fluoride removal. Nonelectrostatic model-Generalized composite approach had successfully described and predicted the adsorption process. —SF and —SOHF– formed in the removal of fluoride via the ligand exchange and surface complexation.
