摘要
以二乙烯三胺和马来酸酐为单体合成了马来酰二乙烯三胺酸(Tri-acid),并以Tri-acid为交联剂与β-环糊精(β-CD)反应得到β-CD/Tri-acid交联聚合物(PCD-tri)。用IR,1H NMR,TG等方法分析了PCD-tri的结构,研究了PCD-tri对碱性品红(BF)和亚甲基蓝(MB)染料的吸附性能。实验结果表明,合成PCD-tri适宜的投料比为:n(β-CD)∶n(Tri-acid)=1∶20。PCD-tri对BF染料适宜的吸附条件为:ρ(BF)=300 mg/L、吸附时间240 min、溶液pH=6.34,在该条件下,PCD-tri对BF染料的饱和吸附量为94.17 mg/g;对MB染料适宜的吸附条件为:ρ(MB)=225 mg/L、吸附时间300 min、溶液pH=6.00,在该条件下,PCD-tri对MB染料的饱和吸附量为82.97 mg/g。
A novel β-cyclodextrin polymer（PCD-tri） was prepared from fl-cyclodextrin（fl-CD） and crosslinking agent diethylenetriamine maleamic acid （Tri-acid） which was synthesized by the reaction of maleic anhydride and diethylenetriamine. The structure of PCD-tri was characterized by means of FTIR, 1H NMR and TG, and its adsorptivity to two dyes, basic fuchsin（BF） and methylene blue（MB）, was studied. The results indicated that the optimum ratio of n（β-CD） ： n（Tri-acid） was 1 ： 2.0 for the synthesis of PCD-tri. As for PCD-tri adsorbing BF dye, under the optimum conditions ofp（BF） 300 rag/L, 240 min and solution pH 6.34, the saturated adsorption quantity was 94.17 mg/ g; as for PCD-tri adsorbing MB dye, under the optimum conditions ofp（MB） 225 mg/L, 300 min and solution pH 6.00, the saturated adsorption quantity was 82.97 mg/g.
