Activated carbon is a typical adsorbent, which has the advantages of large specific surface area, good selectivity, and strong adsorption capacity. However, activated carbon can only be temporarily adsorbed. As the temperature and wind speed increase, the adsorbed pollutants may be released. , and the activated carbon after use needs to be regenerated, regeneration will lead to a loss of 10-15% of activated carbon, and the price of activated carbon is relatively high, which limits its application

[0025] 1. Preparation of three-half water four-protonated hydrated cadmium hexahydroxyborate vanadate with adsorption properties:
[0026] The crystals grown by the hydrothermal synthesis method were weighed successively vanadium triacetylacetonate (0.7mmol, 0.2431g), H 3 BO 3 (9.9mmol, 0.6151g), Cd(CH 3 COO) 2 2H 2 O (0.2mmol, 0.0558g) and ethanolamine (0.1ml) were placed in a 15ml high-pressure reactor lined with polytetrafluoroethylene, and then distilled water (2.5ml) was added to it in turn, and then stirred for 10min until the mixture was evenly mixed , Install the reactor. After the mixture was crystallized in a thermostat at 100° C. for 6 days, the reactor was taken out, and allowed to cool naturally to room temperature. Suction filtration, rinse with distilled water, and then dry naturally in the air to obtain black crystals, which are three-half water four-protonated cadmium hexahydroxyborate vanadate.

The invention discloses a microporous boron vanadate compound with adsorption performance and a preparation method of the microporous boron vanadate compound. The structural formula of the microporous boron vanadate compound is as shown in the specification. According to the preparation method, crystals grows in a hydrothermal synthesis method, triacetyl acetylacetonate, H3BO3, Cd(CH3COO)2.2H2O, ethanolamine and distilled water are sequentially added into a high-pressure reaction kettle with a polytetrafluoroethylene lining to obtain a mixture; and the mixture is stirred for 10 minutes, the reaction kettle is placed in a constant-temperature box at 100 DEG C to carry out the crystallization for 8 days to obtain a product. The microporous boron vanadate compound has advantages that the preparation method has advantages of simple process, high efficiency, low price, no pollution, good repetition and the like.
Description
technical field [0001] The invention relates to a microporous boron vanadate compound with adsorption performance and a preparation method thereof. Background technique [0002] With the rapid development of my country's dye and printing and dyeing industries, the annual national dye wastewater discharge accounts for 35% of the total industrial wastewater discharge. Dye wastewater has deep chroma, complex components, and large changes in water quality. After entering the water body, it will affect the photosynthesis of aquatic plants, thereby destroying the ecological balance in the water, and the anti-photolysis, anti-oxidation, and anti-biodegradation capabilities of dyes are becoming stronger and stronger. Conventional methods are difficult to control and have brought serious pollution to the environment. [0003] At present, the research on the adsorption of colored dye wastewater and related impurities is mainly focused on porous adsorbents such as activated carbon, ci...
