[Display omitted] ⿢A novel method for direct removal of As(III) by forming tooeleite is developed.⿢Arsenic removal efficiency can reach 99% for high As(III) concentration of 7.5g/L.⿢Ferrihydrite contributes to the formation of tooeleite and the removal of As(III). In this study, an earth-mimetic met...
