NOVELTY - Composition and its preparation method are claimed. The composition comprises 80-90 pts. wt. amine modified straw, 1-10 pts. wt. graphene oxide and 1-10 pts. wt. cyclodextrin. The method involves slowly adding amine modified straw, graphene oxide and cyclodextrin into bath of deionized water in ratio of 1:10-20, sonicating the mixture for a period of time, and freeze-drying the sonicated product. USE - As composition. ADVANTAGE - The reusable composition is environmentally-friendly, and has good mechanical properties, regular organizational structure, high porosity, high adsorption capacity, and improved adsorption rate.
