研究了交联β-环糊精聚合物对水溶液中苯酚的去除作用。对于甲酚，甲基的位置影响与环氧氯丙烷交联的环糊精聚合物的相互作用，对甲酚是吸附最多的一种。在苯酚的情况下，等量吸附热几乎是恒定的表面覆盖度，但变化的甲酚。当与用于从水中提取苯酚的其他典型吸附剂（活性炭、大孔树脂Lewatit OC 1064和藻酸钙）相比时，与不同试剂（表氯醇、琥珀酰氯和两种二异氰酸酯）交联的环糊精聚合物显示出高吸附能力，特别是在高苯酚浓度下。(c)2007爱思唯尔有限公司保留所有权利。
The removal of phenols from aqueous solutions by crosslinked P-cyclodextrin polymers has been studied. For cresols, the position of the methyl group influences the interaction with cyclodextrin polymers crosslinked with epichlorohydrin, being p-cresol the most adsorbed one. The isosteric heat of adsorption is almost constant with the surface coverage in the case of phenol, but varies for the cresols. When compared with other typical sorbents used to extract phenol from water (activated carbon, the macroporous resin Lewatit OC 1064, and calcium alginate), cyclodextrin polymers crosslinked with different reagents (epichlorohydrin, succinyl chloride and two diisocyanates) show high sorption capacities, especially at high phenol concentrations.
