摘要

利用,60,Co γ为辐射源，在氮气保护下对黄原胶（Xanthan gum，XG）和丙烯酰胺（Acrylamide，AM）进行共辐射接枝，制备出了黄原胶/丙烯酰胺接枝共聚物（Xanthan gum-graft-Acrylamide，XG-g-AM）。研究了反应条件对样品接枝率和单体转换效率的影响规律，利用元素分析（Element analysis，EA）、傅立叶红外光谱（Fourier-transform infrared spectroscopy，FT-IR）、X射线衍射（X-ray diffraction，XRD）、热重分析（Thermal gravimetric analysis，TGA）对接枝产物进行表征。实验结果表明，当XG浓度为10 g/L，AM与XG质量比为3∶1，吸收剂量为6.0 kGy，其最佳产品接枝率为128.5 %，单体接枝效率为80.4 %。同时对接枝共聚物的絮凝效果进行了试验。

Abstract

Xanthan gum-graft-Acrylamide (XG-g-AM) was synthesized by ,60,Co γ-rays radiation. The effects of the different reaction conditions on the grafting degree and the grafting efficiency were explored. The structures of the grafted copolymers were characterized by means of Element Analysis (EA), Fourier-Transform Infrared Spectroscopy (FT-IR), X-Ray Diffraction (XRD), Thermal Gravimetric Analysis (TGA) respectively. The experiment results show that the optimized grafting reaction parameters, XG concentration of 10 g/L, AM and XG Mass ratio of 3:1, the total absorption dose of 6.0 kGy can make the grafting degree up to 128.5 % and the grafting efficiency to 80.4 %. And the flocculation performance of XG-g-AM has been also confirmed.
