▎ 摘  要

NOVELTY - An arsenic sorbent has granular activated carbon with a developed microporous structure, which gives the carbon a specific surface area of over 700 m2/g, the surface of which is covered with a composition of highly oxidized graphene oxide in an amount of 2-4% and iron (II) and (III) oxide in an amount of 2% and 4%, where the arsenic sorbent is prepared by providing graphene oxide, directly synthesizing iron (II) oxide and (III) oxide with graphene oxide in an amount of 2 wt.% applying to the obtained graphene oxide, and applying the composition of graphene and iron oxides to the dried activated carbon. USE - Arsenic sorbent.
