USE - Method for preparing graphene-calixarene-iron(III) oxide (claimed). ADVANTAGE - The product can be recycled. DETAILED DESCRIPTION - A graphene-calixarene-iron(III) oxide is prepared by dissolving 1.0 mg calixarene and 9.0 mg graphene oxide (GO) in water under ultrasonic condition, mixing and stirring for 24 hours, high speed centrifuging for 20 minutes at speed of 10000 revolutions/minute (rpm), washing, drying into vacuum oven for 48 hours to obtain GO-T, weighing 10 mg GO-T, respectively adding 100 mu l hydrazine hydrate and 200 mu l ammonia, heating to 75 degrees C, magnetically stirring to react for 8 hours, centrifuging, water washing, centrifuging, repeating for 3 times, washing once with ethanol, drying into vacuum box to obtain product RGO-T, ultrasonically mixing 10 mg iron(III) oxide nanoparticle (Fe3O4NPs) with particle diameter of 5 nm and 10 mg RGO-T, stirring at room temperature for 24 hours, high speed centrifuging for 10 minutes at speed of 10000 rpm, washing, and vacuum drying at 65 degrees C for 48 hours to obtain RGO-T-Fe3O4NPs. An INDEPENDENT CLAIM is included for preparation of graphene-calixarene-iron(III) oxide comprising taking 17.5 mg RGO-T-Fe3O4NPs, 3.0 ml of 30% hydrogen peroxide and 10 ml of 5asterisk105 methylene blue, adding to 200 ml beaker, uniformly stirring under catalytic conditions at 25 degrees C at pH of 5.5, degrading methylene blue reaching degradation rate to 100%, and catalyst circulating for 5 times ensuring degradation to more than 98%.
