NOVELTY - Preparing rubber seed-shell matrix composite material comprises (i) pulverizing the rubber seed husks to 20-200 meshes, mixing with potassium hydroxide, and performing temperature-programmed heat treatment in a nitrogen atmosphere, (ii) mixing MXene, graphene oxide, auxiliary agent, coupling agent and water to obtain dispersion, (iii) immersing the rubber seed husks treated in the step (i) in the dispersion of step (ii) at 30-300degrees Celsius, and reacting with high-speed stirring for 2-48 hours, and (iv) taking the product of step (iii), filtering, washing and drying, immobilizing MXene-graphene oxide on the surface of rubber seed shell by thermosetting method through the action of coupling agent to obtain rubber seed shell matrix composite material. USE - The material is useful as creatinine and uric acid scavenging agent (claimed). ADVANTAGE - The material has high clearance of creatinine and uric acid by the composite material as 431 mg/g and 504 mg/g and excellent creatinine uric acid scavenger.
