溶剂浸渍树脂填补了液-液萃取和离子交换之间的空白。已经发现溶剂浸渍树脂可以广泛用於很多过程,比如化学分析、工艺分离和从废水中除去金属离子等。本文研究了溶剂浸渍树脂的性能与基体结构、萃取剂在树脂中的含量及分布的关系,指出了“理想”溶剂浸渍树脂应当满足的要求。
Solvent impregnated resin fills the gap between liquid-liquid extraction and ion exchange. Solvent impregnated resins have been found to be widely used in many processes such as chemical analysis, process separation and the removal of metal ions from wastewater. In this paper, the relationship between the properties of solvent-impregnated resin and the matrix structure, the content and distribution of extractant in the resin was investigated. The requirements of the “ideal” solvent-impregnated resin should be satisfied.
