    摘要: 金属离子是环境监测的重要内容之一。虽然现代分析仪器有了很大的发展,但在进行环境样品中的痕量组分分析时,由于方法的灵敏度不够及大量共存元素的干扰,直接测定很困难。所以在环境监测中,复杂样品需要经过一定的预处理——分离富集以后才能进入分析仪器进行准确的测定。而样品的富集分离通常需要借助选择性高、吸附容量大的各种吸附材料。介绍了吸附材料的分类,吸附材料的发展,吸附材料的原理,吸附材料的比较,并着重介绍了各种吸附材料在环境监测和环境保护中的应用。Metal ions are one of the important contents of environmental monitoring. Although many modern analytical instruments have been developed recently and reached trace level or super trace level sensitivity, the direct analysis for environmental samples is still difficult because of the high complexity of samples and severe interference caused by matrix effects. So, various pre-treatment procedures are necessary before the more accurate measurement by analytical instruments in environmental monitoring area. It is obvious that the pre-treatment procedures of trace elements depend on different functional adsorption materials with higher selectivity and adsorption capacity. The classifications of ad- sorption materials, the development of adsorption materials, the principles of adsorption materials and the comparisons of adsorption materials were introduced. The application of adsorption materials in environmental monitoring area and environmental protection area were introduced in detail.
