Molecularly imprinted polymer based PVC-membrane-coated graphite electrode for the determination of metoprolol
MS Tehrani, MT Vardini, PA Azar… - International Journal of …, 2010 - Elsevier
A PVC membrane based on metoprolol molecularly imprinted polymer (MIP) coated directly
on graphite electrode for determination of metoprolol in real sample is described. This
potentiometric sensor was designed by dispersing the MIP particles in dioctylphthalate
plasticizer as solvent mediator and then embedded in polyvinyl chloride matrix. The
electrode exhibits a near Nernstian of 55.4±1 mV decade-1 for metoprolol over a wide
concentration range between 2.0× 10-7-8.0× 10-3 M and a detection limit of 1.26× 10-7 M. It …

[引用][C] Molecularly Imprinted Polymer (MIP) Based PVC-Membrane-Coated Graphite Electrode for the Determination of Heavy Metals
A PVC membrane based on molecularly imprinted polymer (MIP) coated directly on graphite
electrode for determination of heavy metals in real soil sample is describes. The composite
membranes have been prepared by using methacrylic acid (MAA) as functional monomer
and ethylene glycol dimethyl acrylate (EGDMA) as cross linker. MAA was chosen as a
functional monomer, as it capable of strong electrostatic interactions with heavy metals. The
chemical behaviour of the thin film (MIP) were characterized using Scanning Electron …
