NOVELTY - Graphene composite oxide modified attapulgite water purifying agent comprises 10-15 pts. wt. graphene oxide, 20-35 pts. wt. attapulgite, 2-5 pts. wt. hexadecyl trimethyl ammonium bromide, 1-3 pts. wt. dodecyl benzene sulfonic acid, 5-12 pts. wt. calcium powder, 5-10 pts. wt. polyvinyl alcohol, 3-8 pts. wt. polyaniline, diluted hydrochloric acid and de-ionized water. USE - Graphene composite oxide modified attapulgite water purifying agent. ADVANTAGE - The graphene composite oxide modified attapulgite water purifying agent is eco-friendly, has super large specific surface area and good water purifying effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene composite oxide modified attapulgite water purifying agent, which involves: (A) adding attapulgite into deionized water, stirring for 30-60 minutes to disperse uniformly, adding hexadecyltrimethyl ammonium bromide and stirring for 8-10 hours, filtering and drying attapulgite to obtain modified; (B) adding modified attapulgite into deionized water, stirring and dispersing ultrasonically for 30-60 minutes to obtain modified attapulgite dispersion; (C) adding oxidized graphene into de-ionized water, performing ultrasonic treatment for 30-60 minutes, forming uniformly dispersed graphene oxide dispersing liquid; (D) mixing polyvinyl alcohol, mixing polyaniline solution into ultrasonic for 30 minutes to obtain mixed solution A in graphene oxide dispersion; (E) stirring modified attapulgite dispersion ultrasonically and mechanically, adding calcium aluminate powder, dodecyl benzene sulfonic acid, mixing ultrasonically, stirring mechanically for 2-3 hours; and (F) using diluted hydrochloric acid to adjust pH to 2, standing, washing by de-ionized water for three times and centrifuging to obtain precipitate, drying in vacuum and grinding into powder to obtain water purifying agent.
