Patent Title: Preparation method of pyrethroid pesticide type molecularly imprinted membrane
Publication date: 2015
Publication number: CN104311744

Abstract: The invention discloses a preparation method of a pyrethroid pesticide type molecularly imprinted membrane. The preparation method is characterized by comprising the following steps: firstly performing ultrasonic washing on an LDPE (low-density polyethylene) membrane with anhydrous ethanol, acetone and distilled water respectively, performing vacuum drying, placing into a reaction chamber of a plasma treatment instrument, introducing argon gas and performing surface activation treatment; then placing the LDPE membrane after activation treatment into a molecular imprinting grafting solution to graft under nitrogen production conditions; taking out the molecularly imprinted membrane after the grafting reaction, and eluting with an organic solvent to remove template molecules till the template molecules can not be detected by GC-ECD (gas chromatography with an electron capture detector); and finally performing vacuum drying on the molecularly imprinted membrane after removal of the template molecules. The preparation method has the advantages that the pyrethroid pesticide type molecularly imprinted membrane has relatively high selective permeability against pyrethroid pesticide residues, can be applied to selective separation and efficient enrichment of pyrethroid pesticides in aquatic products and other complex biological samples, and has relatively high application values.
