Embodiment Construction

[0030] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below in conjunction with specific embodiments and illustrations.

[0031] Preparation of metal-organic microporous cobalt compound (1):

[0032] The mixture obtained by mixing 0.10 mmol of 2,5-bis(4-pyridyl)pyrimidine and 0.10 mmol of 1,3,5-tris(4-carboxyphenyl)benzene was mixed with 0.20 mmol of cobalt sulfate CoSO 4 Put them together in a 10mL reaction kettle, add 2mL of N,N-dimethylformamide solvent and 1mL of deionized water, and then add NaOH dropwise to make the solution a clear liquid. Seal and heat to 105° C., continue heating for 5 days, and then cool down to room temperature at a rate of 5° C. / h. At this time, red blocky crystals are precipitated in the small glass bottle, and the yield is 55%. Calculated: C: 61.58; H: 4.64; N: 9.21. Experimental values: C: 61.14; H: 4.94; N: 9.57%....

Abstract

The invention discloses a preparation method and application of a metal-organic microporous cobalt compound, and relates to the technical field of coordination compounds; the metal-organic microporouscobalt compound is prepared from cobalt sulfate CoSO4, an organic ligand 2, 5-bis (4-pyridyl) pyrimidine and 1, 3, 5-tri (4-carboxyphenyl) benzene as raw materials by a hydrothermal synthesis methodin the presence of a reaction solvent; the compound 1 synthesized by the invention is of a two-dimensional microporous structure, has a plurality of active sites and is very novel in structure; the compound 1 with the active sites is combined with nanogold to modify a glassy carbon electrode. The modified glassy carbon electrode shows good selectivity, high stability and sensitivity and a wide detection range for detection of Pb < 2 + > ions.

Description

Technical field: [0001] The invention relates to the technical field of coordination compounds, in particular to a preparation method and application of a metal-organic microporous cobalt compound. Background technique: [0002] Breaking σ-σ bonds or coupling σ-σ bonds between pyridine rings is very important in the synthesis of compounds, but due to the high stability of pyridine rings, it is very difficult to break σ-σ bonds or couple σ-σ bonds between pyridine rings Yes, scientists have been looking for suitable reaction conditions, but so far, there are few reports on σ-σ bond breaking or σ-σ bond coupling between pyridine rings, and the reaction conditions are harsh. [0003] Heavy metal pollution has always been a very serious environmental problem, especially mercury, cadmium, lead and other heavy metal ions with significant and biological toxicity. Once these ions enter the environment, they are not easily degraded by microorganisms, but can only undergo mutual trans...
