Publication date: 2012
Publication number: CN102393411

Abstract: The invention discloses a preparation method of an electrochemical sensor for detecting molecular imprinting of organophosphorus pesticide residue. The method comprises the following steps of: firstly preparing a solution from the raw molecules of organophosphorus pesticide serving as imprinting molecules and a functional monomer and an electrolyte; depositing the molecular imprinting polymer on the surface of a working electrode by an electrochemical polymerization method so as to finish the preparation of a molecular imprinting sensitive film; and removing the imprinting molecules of the organophosphorus pesticide from the molecular imprinting sensitive film by a proper elution method and a proper eluent so as to finish the preparation of the electrochemical sensor. The method disclosed by the invention has the advantages of fast response, high sensitivity and good selectivity; and meanwhile, the detection method is simple and quick, has strong adaptability after being popularized and particularly strong universality in pesticide detection, and has a wide market prospect.
