Abstract

The invention provides a method for preparing a metal-organic framework material HKUST-1 from copper-containing industrial wastewater, belonging to the technical field of wastewater utilization. The method comprises the following steps: mixing the copper-containing industrial wastewater with trimesic acid, and carrying out a coordination reaction to obtain a crude reaction product, wherein the pH value of the copper-containing industrial wastewater is 0.4 to 1.5; and mixing the obtained crude reaction product with an activating agent, and carrying out activating treatment to obtain the metal-organic framework material HKUST-1. The metal-organic framework material HKUST-1 is prepared from the copper-containing industrial wastewater, so cost is low, copper ions in the industrial wastewater can be removed, and environmental pollution is reduced. A result of an embodiment shows that the HKUST-1 is successfully prepared by the method disclosed by the invention.

Description

technical field [0001] The invention relates to the technical field of waste water utilization, in particular to a method for preparing metal-organic framework material HKUST-1 from copper-containing industrial waste water. Background technique [0002] Metal-organic frameworks (MOFs) are a kind of network framework materials with porous structure, large specific surface area and regular crystal structure formed by combining metal ions and heterogeneous organic ligands through coordination chemistry. Compared with traditional porous materials, it has a porosity of up to 90% and a specific surface area greater than 6000m 2 / g characteristics, and its structure can be adjusted by adjusting the pore size and changing the type of organic ligands so that it can be applied in many fields such as hydrogen storage, drug carrier, catalysis, fluorescence, biosensor, gas adsorption and separation, supercapacitor, etc. , and exhibited excellent performance. [0003] HKUST-1 is a typic...
