摘要:

α-甲基苯乙烯和马来酸酐为共聚物单体,二乙烯基苯为交联剂,通过自稳定沉淀聚合制备交联α-甲基苯乙烯马来酸酐共聚物微球(PAMSM);用对甲苯磺酰氯对β-环糊精(β-CD)进行单磺酰化得到单-6-对甲苯磺酰基-β-环糊精(mono-6-OTs-β-CD),其与过量的1,2-丙二氨反应制备得到1,2-丙二胺基-β-环糊精(PDM-β-CD);通过PDM-β-CD的伯氨与PAMSM的酸酐开环酰胺化反应,将β-CD固载在PAMSM上制备微球β-CD-PDM-PAMSM。采用傅里叶红外光谱(FTIR)、扫描电子显微镜(SEM)、元素分析对β-CD-PDM-PAMSM的结构、表面形貌和组成进行表征。结果表明,β-CD-PDM-PAMSM具有良好的球形度,平均粒径在1.08µm;β-CD固载率高,通过元素分析计算得β-CD固载率为53.1%。将PAMSM、β-CD-PDM-PAMSM、水解PAMSM(H-PAMSM)和水解β-CD-PDM-PAMSM(H-β-CD-PDM-PAMSM)作为吸附剂,研究其对亚甲基蓝溶液(MB)的吸附性能。研究表明,PAMSM对MB的吸附能力为25.3mg/g,β-CD-PDM-PAMSM对MB的吸附能力比PAMSM提高了615.8%,水解后的H-β-CD-PDM-PAMSM和H-PAMSM对MB的吸附能力较PAMSM分别提高了1043.5%和860.8%。

Abstract:

Cross-linked α‍-methylstyrene maleic anhydride copolymer microspheres (PAMSM) were prepared by self-stable precipitation polymerization with α‍-methylstyrene and maleic anhydride as copolymer monomers and divinylbenzene as crosslinking agent. Firstly, mono-6-p-toluenesulfonyl-β- cyclodextrin (mono-6-OTs-β-CD) was obtained by the monosulfonylation of β-cyclodextrin (β-CD) with p-toluenesulfonyl chloride, and then 1,2-propylenediamine-‍β‍-cyclodextrin (PDM-‍β‍-CD) was achieved by the ammoniating of mono-6-OTs-β-CD with excess 1,2-propylenediamine. The microspheres of β-CD-PDM-PAMSM were prepared though immobilizing PDM-β-CD to the PAMSM by ringing-open amidation reaction of PDM-β-CD with the primary amines and PAMSM with the anhydride groups. The composition, surface morphology, particle size and distribution of the β-CD-PDM-PAMSM were characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and elemental analysis. The results showed that the β-CD-PDM-PAMSM maintained good sphericity and the average particle size was 1.08μm. The immobilization yield of β-CD on PAMSM was high, and the grafting rate of β-CD was 53.1% calculated by the elemental analysis. Then, the adsorption properties for methylene blue solution (MB) of PAMSM, β-CD-PDM-PAMSM, hydrolyzed PAMSM (H-PAMSM) and hydrolyzed β-CD-PDM-PAMSM (H-β-CD-PDM-PAMSM) were investigated. Research suggested that the adsorption capacity of PAMSM for MB was 25.3mg/g, and the adsorption capacity of β-CD-PDM-PAMSM for MB was 615.8% higher than that of PAMSM. The adsorption capacity of H-β-CD-PDM-PAMSM and H-PAMSM for MB was 1043.5% and 860.8% higher than that of PAMSM, respectively.
