摘 要:本实验旨在合成的丙烯酰胺接枝共聚壳聚糖絮凝剂,研究接枝后壳聚糖絮凝剂其优良的絮凝性及投加量小等优点。差示扫描量热分析、红外光谱表征以及粘度测试试验表明丙烯酰胺接枝壳聚糖是成功的。丙烯酰胺与壳聚糖的比例为2:1的时,改性较好。丙烯酰胺接枝后的壳聚糖其絮凝效果显著提高。

Abstract:This experiment is designed to synthesis of acrylamide graft copolymerization chitosan flocculant agent, study after grafting chitosan flocculant its good flocculation sex and dosing quantity small, etc. The acrylamide grafted chitosan was characterized by Fourier transform infrared spectroscopy and differential scanning calorimetry, and the Viscosity test of acrylamide grafted chitosan also was tested. The results showed that acrylamide grafted chitosan was synthesized successfully and the optimal reaction parameters were as following: the ratio of acrylamide and chitosan was 2:1. After acrylamide modified, the flocculation effect was improved significantly.
Key words: chitosan;acrylamide;grafted;characterization
