摘　　要：铬是水和废水严格控制的污染物之一,在各种除铬方法中,吸附法具有低廉高效、操作简单等优点而被广泛关注。本文对具有较好应用前景的吸附剂(矿物、金属氧化物、水滑石类、活性炭、碳纳米管和树脂)除铬的研究现状和最新进展进行了阐述,探讨了各类吸附剂的结构、性能及除铬效能和机理,分析了不同吸附剂的工程应用方法和特点,并对未来吸附技术的重点发展方向做出了展望。Chromium is one of major pollutants strictly controlled in water and wastewater treatments. Adsorption has been considered as an effective technology for its advantages over other methods, such as low cost, high efficiency and simple operation. In this review, promising adsorbents are focused on including minerals, metal oxides, hydrotalcite, activated carbon, carbon nanotubes and resin. Research situation and the latest developments of chromium adsorption are described in detail. Structures, performances and chromium removal mechanisms of various adsorbents are systematically discussed. The engineering application methods and characteristics of different adsorbents are also analyzed. Future development trend of adsorption technology is finally proposed.
