纤维素基超交联吸附树脂的制备及其对苯酚吸附机理的探究
Synthesis of a Cellulose-based Highly Cross-linked Adsorption Resin and its Mechanism for Phenol Adsorption
摘要
Abstract
With cellulose and styrene as raw materials,cellulose grafted styrene hypercross-linked polymer adsorption resin(CGS-HCP)was prepared by the grafting polymerization-diplomatic coupling two-step method.The pore structure and surface chemical properties of the materials before and after preparation were analyzed by BET,XPS,FTIR,SEM and other characterization methods.In addition,the adsorption performance of CGS-HCP for phenol was investigated.The results show that the prepared CGS-HCP has abundant micropores and mesopores,with an average pore size of 3.38 nm and a specific surface area of 525.06 m2/g.Compared with the original cellulose powder CGS-HCP,a large number of benzene ring groups and oxygen-containing functional groups were introduced to further enhance the adsorption of phenol by CGS-HCP.The kinetic and thermodynamic analysis of the phenol adsorption experiment showed that the adsorption process was spontaneous,exothermic and entropy reduction.The maximum adsorption capacity of CGS-HCP for phenol reached 29.438 mg/g,which proved that CGS-HCP had a good removal effect on phenol.The large number of meso-microporous structures inside the resin and the memory groups on the surface of the resin was the main reasons for the strong adsorption.关键词
