An updated review on boron removal from water through adsorption processes

Abstract Boron is an essential micronutrient that has raised much interest, given the narrow balance between its necessity and toxicity. Both natural anthropogenic emissions of boron into water sources can eventually deteriorate quality endanger ecosystem. In this review, we first present a general outline importance boron, chemistry in water, contamination, consequences followed by recent progress removal methods based on adsorption. The adsorbents for deboronation generally be classified functional groups present; chelating groups, metal oxides, layered double hydroxides. To comprehensively address these adsorption methods, detailed discussion reaction mechanism each system done summary field during past 5 years. Finally, some characterization techniques used studies suggestions future research applications together with possible improvements to existing systems are presented. Graphical abstract
