Abstract

The invention relates to a thiol functionalization method and application of a nano hole metal-organic framework material. Through the coordination of the nano hole metal-organic framework material containing a coordination unsaturated active site and a dithiol compound, a certain proportion of thiol in a dithiol compound molecule is connected with the coordination unsaturated active site of the nano hole metal-organic framework material through a coordination bond, and a thiol functional group is grafted to a metal-organic framework, so that the thiol-functionalized nano hole metal-organic framework material is generated. The thiol-functionalized nano hole metal-organic framework material can be used as an adsorption and separation material of heavy metal ions, and is applied to removal of heavy metal ions in a water body.

Description

technical field

[0001] The invention belongs to a sulfhydryl functionalization method of a nano-hole metal-organic framework material and its application in removing heavy metal ions. Background technique

[0002] Nanoporous metal-organic framework materials are a new class of porous materials that have developed rapidly in recent years. This type of material is composed of transition metals and organic ligands as basic components and mainly assembled through coordination bonds. Compared with traditional inorganic porous materials such as zeolites, metal-organic framework materials have the characteristics of diverse structures, unique properties, simple synthesis methods, and mild synthesis conditions. At the same time, this type of material has broad application prospects in many fields such as catalysis, adsorption, ion exchange, selective separation and new sensors. There have been many literature reports on the synthesis of such materials, such as Kitagawa S. et al. in...
