A group of new anion exchangers, based on polyamine podands and of excellent ion-binding capacity, were synthesized. The materials were obtained in reactions between various poly(ethyleneamines) with glycidyl derivatives of cyclotetrasiloxane. The final polymeric, strongly cross-linked materials form gel-like solids. Their structures and interactions with anions adsorbed were studied by spectroscopic methods (CP-MAS NMR, FR-IR, UV-Vis). The sorption isotherms and kinetic parameters were determined for 29 anions. Materials studied show high ion capacity and selectivity towards some important anions, e.g., selenate(VI) or perrhenate.
合成了一组基于多胺配体且具有出色离子结合能力的新型阴离子交换剂。这些材料是通过各种聚乙二胺与环四硅氧烷的缩水甘油基衍生物之间的反应制得的。最终形成的聚合物强交联材料为凝胶状固体。通过光谱方法（交叉极化魔角旋转核磁共振、傅里叶变换红外光谱、紫外可见光谱）研究了它们的结构以及与吸附阴离子的相互作用。测定了29种阴离子的吸附等温线和动力学参数。所研究的材料对某些重要阴离子，如硒酸根（VI）或高铼酸根，显示出高离子容量和选择性。
