A procedure for determining 2,4-dichlorophenoxyacetic acid using immobilized molecular imprinted polymers and an amperometric biosensor

A combined procedure was suggested for determining dichlorophenoxyacetic acid using polyacrylamide-based polymers immobilized in a nitrocellulose matrix with molecular imprints and amperometric cholinesterase biosensors. The sorbability of 2,4-dichlorophenoxyacetic acid on the immobilized polymers and reference polymers was evaluated, and the quantitative characteristics of the sorption-desorption process were calculated.
