Abstract

The invention discloses a phenylboronic acid functionalized Ti3C2Tx magnetic composite material and a preparation method and application thereof. The phenylboronic acid functionalized Ti3C2Tx magnetic composite material is prepared by modifying Ti3C2Tx with a multi-layer structure into amino Ti3C2Tx, namely Ti3C2Tx-NH2, then synthesizing Ti3C2Tx-CTFs-NH2 through further hyperbranched reaction of melamine and cyanuric chloride, and carrying out covalent crosslinking on 4-formyl phenylboronic acid through acetal to synthesize boric acid functionalized Ti3C2Tx, namely Ti3C2Tx-BA; and finally dispersing Fe3O4 nano particles in the surface and interlayer structure of Ti3C2Tx-BA to prepare the phenylboronic acid functionalized Ti3C2Tx magnetic composite material, namely Fe3O4@Ti3C2Tx-BA. The phenylboronic acid functionalized Ti3C2Tx magnetic composite material has the advantages of high adsorption capacity, good selectivity, stable structure, simple and convenient synthesis method, low preparation cost, strong regeneration capability, strong anti-interference capability, short extraction time and the like. The preparation method has the advantages of rapidness, high efficiency, low cost, environmental friendliness, reusability and the like.

Description

technical field

[0001] The invention relates to a separation material, in particular to a phenylboronic acid functionalized Ti 3 C 2 T x Magnetic composite materials and their preparation methods and applications. Background technique

[0002] Catecholamines, including norepinephrine (NE), epinephrine (EP), and dopamine (DA), are neurological substances containing catechol and amine groups, which are involved in various physiological processes in the central and peripheral nervous systems. Plays a vital role in control and regulation. The content changes of catecholamines and their metabolites in the human body have become important indicators in the diagnosis and treatment of Parkinson's disease, Alzheimer's disease, depression and schizophrenia and other diseases. Therefore, the accurate determination of trace catecholamines in biological samples, especially liquid samples, is of great significance to the early diagnosis and treatment of diseases, drug development, bas...
