Preparation of Maleamic Acid Crosslinked β-Cyclodextrin Polymer and Its Application in Adsorption of Methylene Blue
摘要
Abstract
Maleamic acid crosslinked β-cyclodextrin polymer(PMCD) was synthesized by cross-linking β-cyclodextrin with maleamic acid which was prepared from maleic anhydride and ethylenediamine. The structure of PMCD was characterized by means of FTIR. The result shows that there are expected functional groups in PMCD. The effects of the initial mass concentration of methylene blue(MB), temperature and solution pH on the performance of PMCD adsorbing MB were investigated. The results indicate that the adsorption capacity of PMCD to MB increased with the increase of the initial mass concentration of MB. High temperature is favorable for PMCD adsorbing MB. When the solution pH is 2-7, the adsorption capacity of PMCD increases with increasing pH. When the solution pH value is greater than 7, the absorption capacity of PMCA basically keeps constant. The absorption kinetics and isothermal adsorption models of PMCD adsorbing MB were also studied. The kinetic data for PMCD adsorbing MB are in accordance with pseudo-second-order kinetic model and Langmuir isothermal model.关键词
