高分子冠醚是具有选择性配位基的冠醚萃取剂的树脂化形式。这类树脂的离子结合性质与单体极其不同。可以有效地用于各种离子的分离。由E.Blasius合成的酚醛型树脂已用于碱金属、碱土金属、过渡元素、镧系和锕系元素的吸附性能和分离研究。我们用这类树脂作过铀的吸附和有害元素的分离工作,并得到了满意的结果。
The polymer crown ether is a resinized form of a crown ether extractant with selective ligands. The ionic bonding properties of these resins are very different from the monomers. Can be effectively used for the separation of various ions. Phenolic resins synthesized by E. Blasius have been used to study the adsorption and separation of alkali metals, alkaline earth metals, transition elements, lanthanides and actinides. We used these resins for uranium adsorption and separation of harmful elements and obtained satisfactory results.
