NOVELTY - Preparation of graphene oxide modified attapulgite involves mixing attapulgite and graphene oxide dispersion in mixing machine to obtain mixture, heating the mixture, air drying or vacuum drying, and ball milling mixture to desired particle size. USE - Preparation of graphene oxide modified attapulgite for purification of wastewater (all claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for application method of the graphene oxide modified attapulgite, which involves mixing the graphene oxide modified attapulgite and wastewater in mass ratio of 1:100000-1:100, preferably 1:10000-1:1000 to purify water. The mass ratio of attapulgite and graphene oxide in graphene oxide modified attapulgite is 100:2-100:5.
