▎ 摘　　要

NOVELTY - Method for preparing graphene disinfectant involves (a) preparing a water-soluble graphene dispersion, (b) preparing a water-soluble graphene dispersion solution, (c) adding dispersant to the water-soluble graphene solution, and evenly stirring the mixture, (d) continually adding surfactant to the solution, continually stirring the mixture until obtaining uniform mixture, and defoaming it, and (e) allowing it to stand to cool down to room temperature, and filling it in a container to prepare a graphene disinfectant. USE - The method is useful for preparing graphene disinfectant (claimed). ADVANTAGE - The method prepares graphene disinfectant which disinfectant has characteristics of environmental protection, good sterilization effect, long antibacterial time, no pungent odor, and low production cost, and can be applied in daily life areas or public places.
