摘要
以红外光谱、透射电镜及X射线能谱等手段对合成的印迹聚合物的表面形貌和吸附性能进行了表征。结果表明,在吸附动力学中,前2h内吸附量迅速增加,此后缓慢增加,3h后基本达到吸附平衡;吸附行为属于单分子层的吸附,符合Langmiur吸附;温度越高吸附容量越小,说明吸附过程为放热过程;印迹材料具有良好的脱附性能与重复使用性能。
The surface configurations and adsorption abilities of molecular imprinted polymers were characterized by IR、TEM、 XRD and so on.The results showed that： at the dynamics of absorption,the absorption increased at the first 2h and then increased slowly,at the time of 3h reached the balance of absorption.Adsorption behavior belonged to a single molecule layer adsorption,in line with Langmiur adsorption.The higher the temperature,the smaller the adsorption capacity,indicated that the process of adsorption process was exothermic.The imprinted materials had the good desorption performance and the re-use properties.
