Description
Technical Field
The invention belongs to the technical field of organic synthesis and metal organic chemistry, and particularly relates to preparation of a copper complex taking 4,4' -bis (2-methyl-1-imidazolyl) biphenyl and 5-tertiary butyl isophthalic acid as ligands and application of the copper complex in catalyzing photodegradation and adsorbing to remove organic dye in water.
Background
Dye wastewater has high Chemical Oxygen Demand (COD), high organic matter content and poor biodegradability; the chromaticity is high; the components are complex, and the water quality such as pH value and the like has large fluctuation; the toxicity is high, the environmental pollution is serious, and the like, and the influence on the ecological environment and human health is very large.
The production and use amount of azo dyes are the largest of all dyes, and certain azo dyes have been proved to be capable of causing nucleic acid abnormality of human bladder cancer, spleen tumor, liver cancer and test animals and chromosome variation of mammals, and the degradation process of azo dyes is likely to be that azo groups are firstly broken by azo reductase to generate aniline substances, and biological carcinogenic, teratogenic and mutagenic effects of the substances are more serious.
Many reports on the use of zeolite, activated carbon and other materials as adsorbents are made, and little research on the use of complexes as adsorbents for treating dye wastewater is made. Aiming at the current research situation and the deficiency of the related field, the invention discloses a method for treating dye wastewater by using a copper complex, and the dye can be recycled. The complex is used as a novel adsorption material, not only has adsorption property, but also can selectively adsorb dye molecules. In addition, the complex adsorbed organic dye has the advantages of strong binding force, difficult falling, large adsorption capacity, rapidness, high efficiency, less interference by external conditions and the like. Therefore, the complex has potential application value as an adsorbent for treating dye wastewater.
Meanwhile, the complex has better application in the field of photodegradation dyes. The complex has many advantages in photodegradation of dyes compared to semiconductor materials conventionally used for photodegradation: (1) The precision of the crystal structure is beneficial to researching the relationship between the structure and the property of the complex photodegradation dye; (2) The active site capable of coordination promotes the efficient utilization of solar energy by the complex; (3) The porosity and larger specific surface area of the complex can allow dye molecules to pass through the channel rapidly, which is very effective for improving the efficiency of photocatalytic degradation; (4) The interaction of the metal ion of the complex and the ligand can effectively separate the photoelectric electron and the vacancy, thereby improving the photocatalytic activity. Therefore, the complex has high photocatalytic activity and chemical stability, and the synthesis method is simple, so that the complex is an ideal photoreaction catalyst. A series of complexes having photodegradation or dye adsorption properties have been reported, but few complexes having both photocatalytic photodegradation and dye adsorption properties have been reported.
4,4' -bis (2-methyl-1-imidazolyl) biphenyl is a bridging ligand with strong coordination ability: two methylimidazole are arranged at two ends of the ligand, which is beneficial to the synthesis of the complex; the 5-tertiary butyl isophthalic acid can be partially or completely deprotonated, allows different coordination models with metal ions, and is easy to synthesize metal complexes with different dimensions, and the synthesis of structures with different dimensions is a crucial step for completing the device.
The invention belongs to the technical field of organic synthesis and metal organic chemistry, and relates to synthesis of a one-dimensional copper complex, in particular to synthesis of a copper complex with 4,4' -bis (2-methyl-1-imidazolyl) biphenyl and 5-tertiary butyl isophthalic acid as ligands and application of the copper complex in the aspects of catalyzing photodegradation and dye adsorption.
The property of the complex to catalyze photodegradation and adsorb to remove organic dye in water is explored here with cupric ions as the main body and 4,4' -bis (2-methyl-1-imidazolyl) biphenyl and 5-tert-butyl isophthalic acid as ligands.
The copper complex has stable and efficient property of catalyzing photodegradation dye at normal temperature, particularly, the copper complex is used for photocatalysis aiming at methyl orange and methylene blue dye, the methyl orange is basically degraded completely within 70 minutes, the methylene blue is basically degraded completely within 105 minutes, the copper complex is easy to separate and recycle for multiple times, and the catalytic efficiency is basically kept unchanged.
