▎ 摘　　要

NOVELTY - Preparing magnetic surface molecular imprinting electrochemical sensor comprises (i) introducing the magnetic ferroso ferric oxide nano-particle into the graphene oxide to prepare magnetic oxidation graphene the nano material; (ii) using dopamine to modify the magnetic oxidation graphene the nano material to obtain a polydopamine-modified magnetic nano-microsphere; (iii) subjecting the polydopamine-modified magnetic nano-microspheres to surface azide treatment to obtain azide-functionalized magnetic carriers; (iv) introducing the reversible addition-fragmentation chain transfer reagent into the azide-functionalized magnetic carrier by click chemistry, and polymerizing to obtain a magnetic surface molecularly imprinted polymer; and (v) modifying the glassy carbon electrode by the magnetic surface molecularly imprinted polymer. USE - The method is useful for preparing magnetic surface molecular imprinting electrochemical sensor is useful in recognition and detection of tetrabromobisphenol A in an environmental system (claimed). ADVANTAGE - The method prepares magnetic surface molecular imprinting electrochemical sensor with rich and template molecule mass transfer rate thus detects the tetrabromobisphenol A in the sample to be tested with simple principle, readily available raw material cost without any large instrument by realizing the high sensitivity and specificity detection of tetrafluoromethane A. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for magnetic surface molecular imprinting electrochemical sensor, prepared as mentioned above.
