摘　　要：以聚脱氢枞酸/GMA酯微球为吸附剂,研究温度、初始浓度对微球吸附熊果酸的影响,获得熊果酸的最优吸附条件。结果表明:当固液比为0.5 g/L,温度为298 K,初始浓度为40 mg/L时,微球对熊果酸的吸附量达到68.09 mg/g。循环吸附5次后,吸附效率仍达到69.9%。采用红外光谱、扫描电子显微镜、热重等对微球的结构、形貌和热稳定性进行分析,表明微球成功吸附了熊果酸。Poly(dehydroabietic glycidyl methacrylate)microspheres were used as adsorbents to study the effects of temperature and initial concentration on the adsorption of ursolic acid by microspheres and to obtain the optimal adsorption conditions for ursolic acid.The results showed that the adsorption of ursolic acid by microspheres reached 68.09 mg/g when the solid-liquid ratio was 0.5 g/L,the temperature was 298 K,and the initial concentration was 40 mg/L.The adsorption efficiency still reached 69.9%after 5 cycles of adsorption.The structure,morphology,and thermal stability of the microspheres were analyzed by infrared spectroscopy,scanning electron microscopy,and thermogravimetry,which indicated that the microspheres successfully adsorbed ursolic acid.
