摘　　要：水体中氟离子(F^(-))浓度过高会对环境和人体造成危害.吸附法除氟成本低廉、重复利用率高、除氟效果可观,在地下水除氟领域得到广泛应用.氧化铝基吸附材料具有丰富的表面活性位点,对F^(-)的亲和力很强,研究最为广泛.阐述了两种改性活性氧化铝的方法及除氟基本原理,分析了影响吸附的主要影响因素,为氧化铝基吸附除氟的后续研究提供参考,提出研究建议.Excessive concentration of fluoride ions(F^(-))in water can cause harm to the environment and human health.Common methods for fluoride removal in drinking water include adsorption,coagulation precipitation,electrochemical method,membrane separation,etc.The adsorption method has been widely used in the field of groundwater fluoride removal due to its low cost,high reuse rate,and significant fluoride removal effect.Alumina-based adsorption materials have rich surface active sites and strong affinity for fluoride ions,so they are one of the most widely studied adsorption materials at present.This paper describes the methods of metal modification and surface activation of Activated alumina and the basic principle of defluorination,analyzes the main factors affecting adsorption,such as pH,types of coexisting ions,temperature,adsorbent dosage,contact time,etc.which provides a reference for the follow-up research of alumina-based adsorption defluorination,and puts forward research suggestions.
