摘要
通过反相乳液法制备木薯淀粉微球,考察交联剂用量、亲水性乳化剂用量、大豆油用量、淀粉质量分数和搅拌速度对亚甲基蓝(MB)吸附量的影响,得到最佳制备工艺.利用扫描电子显微镜(SEM)、X射线衍射(XRD)和红外光谱(FTIR)进行表征,得到木薯淀粉微球最佳合成工艺:交联剂用量为4.8 mL,亲水性乳化剂用量为0.615 g,大豆油用量为100.0 mL,淀粉质量分数为14%,搅拌速度为1000 r/min;木薯淀粉微球表面粗糙且有小孔,成球性好.
The cassava starch microspheres were prepared by the inverse emulsion method.The effects of crosslinking agent dosage,hydrophilic emulsifier dosage,soybean oil dosage,starch mass fraction and stirring speed on the adsorption capacity of methylene blue(MB)were investigated,and the best preparation process was obtained.It was characterized by scanning electron microscopy(SEM),X-ray diffraction(XRD)and infrared spectroscopy(FTIR).The results show that the optimal synthesis process of cassava starch microspheres was as follows:when the cross-linking agent is 4.8 mL,hydrophilic emulsifier is 0.615 g,soybean oil 100.0 mL,starch mass fraction 14%and stirring speed 1000 r/min;the surface is rough and has small holes with good ball formation.
