不同改性剂制备新型吸附剂除氟的研究进展
Research Progress on Preparation of Novel Adsorbents for Defluorination by Different Modifiers
摘要
Abstract
[Objective]Due to geological reasons and the discharge of fluorine-containing industrial wastewater,the surface water and groundwater environment has been contaminated by fluorideions.Fluorine ion is crucial for human health,but excessive intake of fluorine can have a serious impact on health.Adsorption technology has been widely studied and applied due to its high efficiency and simplicity in removing fluoride ions from water.However,the adsorption effect of traditional adsorbents for fluoride ions is poor,and some may even cause secondary pollution.The new type of adsorbent prepared after modification with a modifier integrates the advantages of fast adsorption,large adsorption capacity and excellent performance,and can effectively remove fluoride ions from water bodies.[Methods]Based on the classification of modifiers such as metallic materials,acids and bases,and organic substances,this paper reviews the research progress on the fluoride removal performance of adsorbents after corresponding modification treatments,and systematically introduces the fluoride removal effects of different metallic materials(transition metals,alkaline earth metals,rare earth metals,post-transition metals,etc.[Results]The modification of metallic materials mainly regulates the surface structure and functional group composition of adsorbents through chemical modification means,thereby achieving efficient removal of fluoride ions.Acid-base modification is usually used as a pretreatment step and is often combined with other modification method.However,organic modification is relatively rare in practical applications,and its mechanism of action is also based on changing the physical and chemical properties of the adsorbent surface to enhance the fluoride removal performance.In addition,the article explores the influence of factors such as pH and coexisting ions on the fluoride removal efficiency,and studies the adsorption mechanism.Finally,the research directions and application prospects of fluoride removal technology by adsorption method are prospected.[Conclusion]Although the new adsorbent prepared after modification has improved the fluoride removal performance,its adsorption effect is usually excellent only under neutral and acidic conditions.Future research should focus on the adaptive optimization of adsorbents to pH environments to expand their practical application potential under different pH conditions.关键词
