【摘要】：系統(tǒng)介紹了無機吸附材料(碳質(zhì)類、礦物類、金屬氧化物類)、有機高分子吸附材料(纖維素、殼聚糖、農(nóng)林廢棄物、離子交換樹脂等)和復(fù)合型吸附材料(有機/有機型、無機/無機型、有機/無機型)等重金屬離子吸附材料的物化特性和結(jié)構(gòu)特點,對上述材料去除水體典型重金屬離子的吸附容量、吸附機理、工程應(yīng)用進展等進行了綜述。闡述了納米材料、離子選擇性材料和可降解生物質(zhì)材料等新型重金屬離子吸附材料的研究現(xiàn)狀及發(fā)展趨勢。結(jié)果表明:開發(fā)價格低廉、吸附容量高、選擇性高、可再生且環(huán)境友好的吸附材料是重金屬離子吸附研究的重要方向;結(jié)合現(xiàn)代化檢測技術(shù)和分析手段,探索吸附過程中吸附劑與重金屬離子間相互作用的本質(zhì),對于拓展吸附機理和開發(fā)性能優(yōu)良的吸附材料具有重要的理論和實際意義。
[Abstract]:Inorganic adsorption materials (carbon, minerals, metal oxides), organic polymer adsorbents (cellulose, chitosan, agricultural and forestry wastes, ion exchange resins, etc.) and composite adsorption materials (organic / available) are systematically introduced. The physical and chemical characteristics and structural characteristics of heavy metal ion adsorption materials such as inorganic / non-model organic / non-type) are reviewed. The adsorption capacity adsorption mechanism and engineering application progress of the above materials for removing typical heavy metal ions from water body are reviewed. The research status and development trend of new heavy metal ion adsorption materials, such as nanomaterials, ion-selective materials and biodegradable biomass materials, are reviewed. The results show that the development of low cost, high adsorption capacity, high selectivity, renewable and environmentally friendly adsorption materials is an important direction of heavy metal ion adsorption, combined with modern detection technology and analytical means, It is of great theoretical and practical significance to explore the nature of the interaction between adsorbent and heavy metal ions in the process of adsorption.
