NOVELTY - Sonochemical synthesis of fluoride ion adsorbent includes dissolving e.g. zirconium oxide chloride octahydrate, Pluronic F127 (RTM: poly(ethylene oxide)-poly(propylene oxide)) block copolymer, aluminum chloride hexahydrate in ethanol to obtain colorless transparent solution, adding oxidized graphene, sonicating, and stirring; adding to deionized water and ethanol mixture, stirring, suction filtering, washing, and drying to obtain crude product; and adding to Soxhlet extractor, adding ethanol and concentrated hydrochloric acid mixture, refluxing, suction filtering, washing, and drying. USE - Method for sonochemical synthesis of fluoride ion adsorbent (claimed). ADVANTAGE - The method has short reaction time, simple operation, high efficiency, and low energy consumption and cost. The adsorbent has high adsorption effect on removing large-range fluoride pollutants in wastewater treatment. DETAILED DESCRIPTION - Sonochemical synthesis of fluoride ion adsorbent comprises: (A) dissolving zirconium oxide chloride octahydrate, Pluronic F127 (RTM: poly(ethylene oxide)-poly(propylene oxide)) block copolymer, aluminum chloride hexahydrate and magnesium sulfate in ethanol to obtain colorless transparent solution; (B) adding oxidized graphene, sonicating, and mechanically stirring for 15 minutes; (C) adding to mixture of deionized water and ethanol at volume ratio of 1:5, stirring for 1 hour, suction filtering, washing filter cake alternately with ethanol and deionized water for 3 times, and drying to 50 degrees C overnight to obtain crude product; and (D) adding to Soxhlet extractor, adding ethanol and concentrated hydrochloric acid mixture at volume ratio of 150:2.3, refluxing to 95 degrees C for 48 hours, suction filtering, washing filter cake alternately with ethanol and deionized water for 3 times, and drying to 50 degrees C overnight. The zirconium oxide chloride octahydrate and aluminum chloride hexahydrate have molar ratio of 1:2-1:0.5. The oxidized graphene and zirconium oxide chloride octahydrate have mass ratio of 1:2.4.
