摘要
以辛可宁为目标吸附分子，采用自由基聚合法制备了一种吸附材料P（Allyl-β-CD）/PSA。利用SEM、FT-IR、TG和DSC对P（Allyl-β-CD）/PSA的外观形貌、结构和热稳定性等进行表征。结果表明，该吸附材料对辛可宁的吸附行为主要是单分子层化学吸附行为，吸附过程符合Langmuir方程和准二级动力学方程。多次吸附实验表明，P（Allyl-β-CD）/PSA对辛可宁有良好的吸附性能，且可多次重复利用，重复使用率为97.1%。
Abstract
With cinchonine as the target molecule to be adsorbed,P(Allyl-β-CD)/PSA adsorption material is prepared by means of free radical polymerization method,and is characterized by SEM,FTIR,TG and DSC.It is verified that the adsorption process is in line with Langmuir equation and the pseudo-second-order kinetic equation,indicating that the adsorption behavior of the adsorbent to cinchonine is mainly monolayer chemisorption behavior.Through experiencing repeated adsorption experiments,it is concluded that P(Allyl-β-CD)/PSA has a good adsorption performance to cinchonine,and can be reused for many times,with a reuse rate of 97.1%.
