摘要
研究了用谷维素作为模板分子,甲基丙烯酸作为功能单体,甲苯作为致孔剂,过氧化苯甲酰为引发剂,二乙烯基苯为交联剂,通过热聚合方法合成分子印迹聚合物(MIP)。之后投放在0.05 mg/mL的谷维素-乙腈溶液中进行绑定测试,根据标准曲线计算谷维素的绑定吸附率初步探索了聚合温度,粒度和超声条件对MIP吸附谷维素效率的影响。得到的最佳条件为:聚合温度60℃,粒度140~200目,在超声条件下谷维素绑定吸附率最大,可达36.50%。
Molecularly imprinted polymers (MIP) was successfully synthesized via thermal polymerization method using oryzanol as template, methacrylic acid as functional monomer, toluene as porogen, benzoyl peroxide as initiator and divinylbenzene as crosslinker. Then it was put in 0.05 mg/mL of oryzanol in acetonitrile solution, and the binding adsorption rate was calculated according to the oryzanol's standard curve. The effects of polymerization temperature, particle size and ultrasonic conditions on MIP adsorption efficiency of oryzanol were explored in this study. The optimal condition: polymerization temperature 60℃, particle size between 140-200, ultrasonic condition. The highest binding adsorption rate is 36.50%.
