Abstract

The invention relates to treatment of dye-containing wastewater, in particular to a two-dimensional supramolecular compound synthesized on the basis of 1,3,5-tri(4-carbonylphenyloxy)benzene and a method and application of the two-dimensional supramolecular compound. The method comprises the following steps: adding 1,3,5-tri(4-carbonylphenyloxy)benzene, phenol and Cu(NO3)2.3H2O into an aqueous solution of acetonitrile, uniformly conducting stirring and mixing, transferring the formed mixture into a reaction kettle with a polytetrafluoroethylene lining, conducting heating to 110-130 DEG C, preserving heat for 60-84 hours, and conducting cooling to 20-30 DEG C at a speed of 3-8 DEG C/h to obtain the two-dimensional supramolecular compound. Compared with the prior art, the invention provides a relatively simple method for synthesizing the two-dimensional supramolecular compound, and the two-dimensional supramolecular compound synthesized by the method has relatively good degradation efficiency on dyes in water; and in addition, tests show that the two-dimensional supramolecular compound synthesized by the method is a stable and recoverable photocatalyst.

Description

technical field [0001] The invention relates to the treatment of dye-containing wastewater, in particular to a two-dimensional supramolecular compound synthesized based on 1,3,5-tris(4-carbonylphenyloxy)benzene and a method thereof, and a two-dimensional supramolecular compound based on the two-dimensional supramolecular compound Application to the degradation of dyes in water. Background technique [0002] Azo dyes containing -N=N- groups are the main pollutants in wastewater. Most dyes are difficult to be degraded by microorganisms due to their high stability, and may induce carcinogenic effects in living systems. At present, treatment technologies such as adsorption, membrane separation, and electrochemical degradation have been applied to the removal and treatment of dye wastewater to eliminate and reduce the lasting impact of dyes on biological systems. Photocatalysis is considered to be the most promising method to solve environmental problems. Since the photocatalyt...
