摘要
在氧化还原引发剂过硫酸钾/亚硫酸钠作用下,顺丁烯二酸酐酯化改性的β-环糊精衍生物与阳离子单体甲基丙烯酰氧乙基三甲基氯化铵,通过溶液聚合制得β-环糊精基阳离子型絮凝剂P(β-CD-MAH-co-DMC),用红外光谱、特性粘度、阳离子度等测试方法表征产物的结构与理化性能。脱色实验结果表明,P(β-CD-MAH-co-DMC)与海藻酸钠类阴离子型Polymer X复配处理酸性蓝324染液比单独使用效果好,复配絮凝剂对染液的脱色率更高,脱色速率更快,且耐碱性和耐盐性更优。
Aβ-cyclodextrin(β-CD)based cationic flocculant P(β-CD-MAH-co-DMC)was synthesized by means of aqueous solution polymerization,in which the potassium persulfate and sodium sulfite were used as the initiators,and the derivative ofβ-CD(β-CD-MAH)modified by malefic anhydride and methyl acryloyloxyethyl trimethyl ammonium chloride(DMC)were used as monomers.The chemical structure and properties of P(β-CD-MAH-co-DMC)were characterized through test methods of FT-IR,intrinsic viscosity,cationic degree and so on.The results of decolorization experiment showed that using compound flocculants made up of P(β-CD-MAH-co-DMC)and anionic flocculant called Polymer X mainly including sodium alginate had a better effect on dealing with Acid Blue 324 dye solutions than using P(β-CD-MAH-co-DMC)alone,and the compound flocculant had higher decolorization rate and faster decolorization speed for the dye solution,and its’anti-salt and alkali resistance properties were more excellent.
