Abstract

The invention discloses a preparation method and an application of a magnetic metal - organic nanotube material. The preparation method comprises the following steps of (1) preparation of a Fe3O4 (ferroferric oxide) nanometer material; (2) surface hydroxylation of the Fe3O4 nanometer material: adding the Fe3O4 nanometer material prepared in step (1) into sodium dodecyl sulfate, stirring, and performing ultrasonic reaction; (3) surface silanization of Fe3O4; (4) connecting of the silanized Fe3O4 and 4,4'-biphenyldicarboxylic acid; (5) connecting of the surface of Fe3O4 modified by the 4,4'-biphenyldicarboxylic acid and the metal-organic nanotube material. The prepared metal-nanotube material has the advantages that [Co2(bpdc)1.5(Hbpz] DMF CH3CN H2O crystals of a metal - organic nanotube are radially and uniformly distributed at the surface of Fe3O4, and form a sea urchin shape; a one-dimensional weaving structure is formed by stacking different lengths in an overlapping way, so that the absorbing of polychlorinated biphenyl in a sample is favorable.

Description

technical field

[0001] The invention relates to a preparation method of a magnetic metal-organic nanotube and its application in detecting polychlorinated biphenyls, belonging to the technical field of environmental inspection. Background technique

[0002] Polychlorinated biphenyls are a class of industrial chemicals, which are a class of chlorides formed by replacing the hydrogen atoms on the biphenyl ring with 1-10 chlorines. Due to its characteristics of bioaccumulation, toxicity, and persistence, PCBs became the first batch of persistent organic pollutants included in the controlled list of the "Stockholm Convention on Persistent Organic Pollutants". Polychlorinated biphenyls have good stability, heat resistance and insulation, and can be used as lubricating materials, plasticizers, heat carriers, etc., and are widely used in industrial fields. PCBs can enter the human body through the food chain, causing cumulative poisoning, causing endocrine system disorders, reprod...
