NOVELTY - Adsorbing rhodamine B wastewater by graphene-montmorillonite material involves adding graphene to deionized water, and then placing in an ultrasonic cell pulverizer to ultrasonically disperse and strip the graphene to obtain a 500-1000mg/l graphene suspension. After adding montmorillonite to the glacial acetic acid solution, it is ultrasonically dissolved in an ultrasonic cleaner. The solution is poured into the graphene suspension, and then the system is placed in an ultrasonic washer, ultrasonically stirred, and then electrically stirred to obtain a uniformly dispersed suspension. The mixture is centrifuged and washed with deionized water, and the obtained solid is dried in a freeze-drying oven to obtain a graphene-montmorillonite composite material. The mass ratio of montmorillonite to graphene added is 0.5-0.4:1. USE - Method for adsorbing rhodamine B wastewater by graphene-montmorillonite material. ADVANTAGE - The method enables to adsorb rhodamine B wastewater by graphene-montmorillonite material with high adsorption efficiency, strong thermal stability and less added amount in a cost-effective manner. DETAILED DESCRIPTION - The graphene-montmorillonite material is added to the rhodamine B solution at a volume ratio of the graphene-montmorillonite material to the rhodamine B solution of 1-2g/l at 25-80 degrees C. The sample is analyzed after shaking for 8-12 hours.
