摘　　要：作为去除水中污染物的纳米吸附剂,介孔二氧化硅纳米颗粒(MSNs)对水中各种有毒金属离子表现极高的吸附效率。近期,这一研究领域出现了显著进展,人们有望开发出基于MSNs的水净化技术。本篇综述从MSNs的两种功能化方法(共缩聚和后合成法)出发,列举并分析了关于使用MSNs去除水中金属离子的最新报道,研究和对比分析了新开发的MSNs材料对不同金属离子的最大吸附效率。近期研究趋势表明,大多数工作集中在开发杂化和功能性的多孔二氧化硅纳米颗粒,并将其应用于去除水中的过渡金属以及稀土金属。文章中列举的这些信息将有助于人们设计基于MSNs材料新的研究策略,为该材料在今后废水处理的实际应用提供重要参考。As a nano-adsorbent for removing pollutants in water,mesoporous silica nanoparticles(MSNs)exhibit extremely high adsorption efficiency for various toxic metal ions in water.Recently,significant new progress has been made in this research field,and people are expected to de-velop water purification technology based on MSNs.From this perspective,this review lists and analyzes the latest reports on the use of MSNs to re-move metal ions in water,and compares the maximum adsorption efficiency of newly developed MSNs materials for different metal ions.Recent re-search trends indicate that most work is focused on developing hybrid and functional porous silica nanoparticles and applying them to remove metal ions such as Pb,Cd,Cu and Cr from water.The information presented in this paper will help people to design new research strategies based on MSNs materials and provide important references for the practical application of MSNs materials in wastewater treatment in the future.
