“…Note from the authors of this review: no desorption data included in the manuscript. Calcium alginate caged graphene oxide functionalized with metformin (Alg@ GMet) forming beads is used to investigate the removal from aqueous solutions, both for As(III) and (V) [42]. Best removal rate depended on the arsenic oxidations state: (i) in the (III) state maximum loading resulted in pH values of 2-6, being H 3 AsO 3 the loaded arsenic species, (ii) arsenic(V) is loaded at pH values in the 2-4 range, being H2AsO4-the species removed from the solution.…”

Arsenic, either in (III) or (V) oxidation states forms, is a hazardous elements to humans, thus its removal from aqueous environments is of the utmost priority in the countries where this problem arises. From the various separation technologies, the removal f arsenic via biosorption processing attracted an interest, because besides the removal of the element, allows the recycle materials that in many cases are considered as wastes. The present chapter reviewed the most recent proposals (2022 year) about the use of biosorbents in the removal of this toxic element.
