Embodiment Construction

[0014] (1) Compound (Habtz)BiI 4 Synthesis

[0015] 0.15 g BiI 3 Add 0.025 g of 2-aminobenzothiazole to 25 ml of polytetrafluoroethylene liner, add 4 ml of HI and 1 ml of ethanol, then put the polytetrafluoroethylene liner into a stainless steel reactor, screw it tightly and put it in 120 degrees Celsius oven heating. After keeping the temperature at this temperature for three days, naturally cool to room temperature to obtain a brown-red solution, and naturally volatilize to obtain dark purple strip crystals, which is the compound (Habtz)BiI 4 .

[0016] (2) Mixed solution of selective decolorization of rhodamine B and orange G

[0017] Under dark conditions, mix 20 ml of 9.46 mg / L Orange G and 20 ml of 5.4 mg / L Rhodamine B in a beaker, and adjust the pH to 3.0 with 0.5 mol / L HCl (marked as 0 minutes). Take 20 mg (Habtz) BiI 4 Add to the above-mentioned mixed dye solution, carry out ultraviolet-visible spectrophotometric analysis (4 minutes, 7 minutes, 10 minutes, 14 mi...

Abstract

The invention discloses synthesis of a bismuth iodine based inorganic-organic hybrid material and an application of the hybrid material in selective color fading of rhodamine B. The purpose of the invention is to synthesize the inorganic-organic hybrid material (Habtz)BiI4 which can conveniently, quickly, efficiently and selectively fade color of the rhodamine B, wherein abtz represents 2-aminobenzothiazole. Bismuth iodide, 2-aminobenzothiazole, ethanol and hydroiodic acid can be selected as reaction raw materials, and a single crystal of the compound (Habtz)BiI4 is obtained under the solvothermal synthesis condition. The (Habtz)BiI4 disclosed by the invention has excellent properties, and can be used for chemical selective treatment of the rhodamine B in a dye waste liquid without any energy provided by the outside.

Description

technical field [0001] The invention relates to the field of inorganic-organic hybrid materials, in particular to a bismuth-iodine hybrid material (Habtz) BiI 4 A method for the preparation and application of selective decolorization of dyes, where abtz = 2-aminobenzothiazole. Background technique [0002] In recent years, various industrial wastewater, especially printing and dyeing wastewater, has become more and more polluting to water resources; the country has gradually attached importance to environmental protection, and the rapid, efficient and targeted decolorization of printing and dyeing wastewater has become a new demand growth point. Some low-concentration dye wastewater can be recycled after decolorization treatment, and the pollution to water resources and soil environment is greatly reduced. As an extremely common dye, rhodamine B is widely used in material manufacturing, fabric dyeing, and food processing industries. The World Health Organization has include...
