Bioremoval of antimony(III) from contaminated water using several plant wastes: Optimization of batch and dynamic flow conditions for sorption by green bean husk (Vigna radiata)

•Green bean husk (GBH) among the nine plant wastes investigated for the first time as Sb(III) sorbents.•GBH has shown potential to biosorb Sb(III) in repeated batch and continuous flow modes.•During dynamic column flow, GBH removed Sb(III) to safe drinking water limit of 97% desorption. Regenerated...

Regenerated GBH was reused in seven adsorption–desorption cycles, with
