▎ 摘　　要

NOVELTY - Preparing fluoride adsorbent, comprises mixing aluminum salt and succinate salt uniformly, and separating to obtain fluoride adsorbent. The step of adding magnetic graphene is further included before mixing aluminum salt with succinate salt, or after mixing aluminum salt and succinate salt. USE - The fluoride adsorbent is useful in removing fluoride in water, alkali and neutral water (all claimed). ADVANTAGE - The fluoride adsorbent: has large adsorption capacity; reduces content of fluoride ions in water to less than 0.2 mg/l; achieves purpose of adsorbing low-concentration pollutants; is suitable for surface water remediation projects having large water volume; meets the purification treatment needs of large-flow and large-volume fluoride-polluted surface water; and removes fluoride ions in water and efficiently separates without causing secondary pollution to the water body. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) fluoride adsorbent obtained by above method; and (2) use of fluoride adsorbent in removing fluoride in water, alkali and neutral water.
