氯霉素分子印迹膜的制备及其吸附特性的电化学研究

Preparation of Molecularly Imprinted Film of Chloramphenicol and its Electrochemical Characteristics

试验采用分子印迹技术和电化学聚合物法,在弱酸条件下,以琥珀酸氯霉素为模板分子,邻苯二胺为功能单体,用循环伏安法合成了稳定的琥珀酸氯霉素分子印迹膜,并用差式脉冲法对此印迹膜进行了表征。结果表明,该膜响应快速、灵敏度高、选择性好、具有良好再生性能,在检测氯霉素电化学传感器的研制中具有良好的应用前景。

A stabilized molecularly imprinted film was prepared through the electropolymerization of o-phenylenediamine on a glass-carbon electrode in the presence of template （chloramphenieol suecinate）, based on molecularly imprinting technology and electropolymer, under the condition of weak acidity. And the characteristics of this molecularly imprinted film was determined by differential pulse vohammentry. The results show that the molecularly imprinted film exhibited quick response, good sensitivity, selectivity and recurrence. This film has shown approved prospect in the research of the electro-polymerizations for the detection of chloramphenicol.
