NOVELTY - A kaolin-based water treatment material is prepared by pouring pulverized and sieved kaolin and magnesite raw material, silver-loaded nano-silica material, graphene oxide and manganese dioxide-supported activated carbon material into potassium hydroxide solution, obtaining mixed solution (I), stirring obtained mixed solution, obtaining mixed solution (II), dehydrating obtained solution, obtaining mixed powder, subjecting mixed powder to activation treatment, obtaining activated powder, and subjecting obtained powder to primary heat-treatment process. The potassium hydroxide solution has concentration of 0.5-1 mol/L. USE - Kaolin-based water treatment material.
