| 摘要: |
| 为提高吸附剂对水中双酚A（BPA）的选择识别性能，采用分子印迹溶胶-凝胶技术制备了BPA分子印迹吸附剂（BPA-MIA）.以未添加BPA模板分子制得的非印迹吸附剂（BPA-MNIA）作为比较对象，利用扫描电镜（SEM）、能谱（EDS）、红外光谱（FTIR）、热重分析（TG）对BPA-MIA进行表征，并对其吸附动力学、吸附等温线及选择识别性能进行研究.结果表明，BPA-MIA经过120 min达吸附平衡，吸附过程符合准二级动力学方程及Langmuir吸附等温方程，最大吸附容量为16.69 mg/g，比BPA-MNIA吸附容量提高5倍，对BPA具有较高的选择吸附性能. |

| Abstract: |
| Bisphenol A molecularly imprinting adsorbent (BPA-MIA) was synthesized by the molecular imprinting technique with a sol-gel process in order to improve the selectivity in water.The prepared BPA-MIA was characterized using SEM,EDS,FTIR and TG，and the characters of adsorption and selective recognition were investigated comparing to BPA molecular non-imprinting adsorbent (BPA-MNIA) without BPA temple.The results showed that the adsorption equilibrium time was 120 min.The equilibrium data fitted well to the pseudo-second-order kinetic and the Langmuir model for BPA binding onto BPA-MIA,respectively.The maximum capacity was 16.69 mg/g which was five times higher than that of BPA-MNIA,and it had a high selective adsorption for the imprinted BPA in water phase. |
