摘要:
为了制备一种具备高效处理污水能力的新型絮凝剂,以丙烯酰胺为醚化剂,在碱性条件下通过迈克尔加成反应合成了魔芋葡甘聚糖醚类衍生物(AMKGM)。以傅里叶变换红外光谱、核磁共振氢谱、X射线衍射、热分析仪和扫描电子显微镜对AMKGM的结构和形貌进行表征。并以AMKGM为新型絮凝剂,研究其对蒙脱土溶液的絮凝性能,考察了絮凝剂的质量分数、絮凝时间、絮凝温度和pH值等主要因素的影响。研究结果表明:成功制备了AMKGM絮凝剂,当絮凝时间为90 min,絮凝剂质量分数为0.75%时,在酸性和碱性条件下,AMKGM都表现了良好的絮凝效果,最高絮凝效率为98%,重现性好,且实验温度范围内对AMKGM的絮凝性能没有显著的影响。

Abstract:
In order to prepare a novel flocculant with high efficiency for wastewater treatment, konjac glucomannan ether derivative (AMKGM) was synthesized under alkaline conditions using acrylamide as the etherifying agent via Michael addition reaction. The structure and morphology of AMKGM were characterized by Fourier transform infrared spectroscopy, proton nuclear magnetic resonance spectrometry, X-ray diffraction, thermogravimetric analyzer, and scanning electron microscope. Employing AMKGM as a new flocculant, its flocculation performance on montmorillonite solution was investigated, exploring the effects of flocculant mass fraction, flocculation time, flocculation temperature, and pH value as major factors. The research results indicate that the AMKGM flocculant was successfully prepared. When the flocculation time is 90 minutes and the mass fraction of the flocculant is 0.75%, good flocculation effects are observed for AMKGM under both acidic and alkaline conditions, with the highest flocculation efficiency reaching 98%. The reproducibility is excellent, and within the experimental temperature range, there is no significant influence on the flocculation performance of AMKGM.
