中文摘要：
以可溶性淀粉为原料,通过反相悬浮聚合法,合成了一种交联淀粉微球（CSM）。研究了CSM对羟基苯甲醚的吸附行为,分析了其吸附动力学特性和热力学性质,并利用扫描电子显微镜（SEM）、傅里叶红外光谱仪（FTIR）和X射线衍射仪对淀粉微球及其吸附产物进行了表征,探讨其吸附机理。结果表明：在研究范围内,CSM对对羟基苯甲醚的吸附行为同时符合Langmuir和Freundlich等温吸附方程;在不同温度下,CSM吸附对羟基苯甲醚的吸附焓变（ΔH）、吸附熵变（ΔS）、吸附自由能变（ΔG）均为负值,吸附是一个自发、放热过程。
英文摘要：
The crosslinked starch microspheres（CSM）were synthesized from soluble starch by inverse suspension polymerization.The adsorption behavior of CSM for p-hydroxyanisole was investigated.The kinetics and thermodynamics characteristics were also studied.The structures of CSM before and after adsorption were characterized by particle size analyzer,scanning electron microscope,FT-IR spectroscopy and X ray diffraction（XRD）,and the mechanism of adsorption was also discussed.Within the framework of the study,the adsorption characteristics of CSM for p-hydroxyanisole obeyed the Langmiur and Freundlich adsorption isotherm equations.The enthalpy change ΔH,entropy change ΔS and free energy change ΔG for p-hydroxyanisole adsorbed by CSM were all negative at different temperatures.The adsorption was a spontaneous and exothermic process.
