Method for preparing cuprous oxide

Abstract

The invention discloses a method for preparing cuprous oxide and belongs to the technical field of cuprous oxide preparation.The method includes the steps that bottom mud of a metallurgy sewage treatment plant is collected, after the bottom mud is mixed with water and a mercury nitrate solution and centrifuged, supernate containing mercury clostridium is obtained, then a culture solution is prepared from methyl cobalt ammonia, glycine betaine and the like, rocking bed shaking culture is conducted on the culture solution, after standing and filtering are conducted, triphosadenine is added to filtrate and mixed, diethyl ether is added for extraction, formaldehyde is added to extraction liquor, after anaerobic reduction is conducted, the mixture is mixed with copric chloride dihydrate and soaked for a reaction, starch is added for anaerobic fermentation, then aeration is conducted on the mixture, centrifugation is conducted, sediment on the lower layer is taken, and the cuprous oxide is obtained after washing, drying and grinding are conducted.The method has the advantages that the preparation steps are simple, purity of an obtained product is 19.2% or above higher than that of other products, and the particle size is small and uniform; particles are not prone to clustering in the formation process, dispersing performance is high, and the yield is raised by 30-40%.

Description

technical field [0001] The invention relates to a method for preparing cuprous oxide, which belongs to the technical field of cuprous oxide preparation. Background technique [0002] Cuprous oxide is an oxide of monovalent copper, bright red powdery solid, almost insoluble in water, disproportionated into divalent copper and simple copper in acidic solution, and gradually oxidized into black copper oxide in humid air. It is a P-type semiconductor material with a wide range of uses. It is not only used as a catalyst in organic synthesis, but also used in the manufacture of ship bottom antifouling paint, insecticides, various copper salts, analytical reagents, red glass, and copper plating and plating. The preparation of copper alloy solution is more used in the field of ceramic devices. Due to the quantum size effect, cuprous oxide has special optical, electrical and photoelectrochemical properties, and has potential applications in solar cells, sensors, superconductors and ...

Problems solved by technology

[0004] The technical problem to be solved by the present invention: aiming at the disadvantages of low purity and large particle size of the cuprous oxide prepared by the current method, the particles are easily agglomerated during formation, and the dispersibility is poor, resulting in low yield. The sediment of the metallurgical sewage treatment plant is mixed with water and mercury nitrate solution and centrifuged to obtain the supernatant of mercury-containing Clostridium difficile, and then the culture medium is prepared with methylcobalamin, betaine, etc., and shaken Vibration culture, after static filtration, add adenosine triphosphate to the filtrate to mix, add ether to extract, add formaldehyde to the extract for anaerobic reduction, mix with copper dichloride for soaking reaction, add starch for anaerobic fermentation, and then It is a method of aerating it, centrifuging to remove the lower layer of sediment, washing, drying and grinding to obtain cuprous oxide, so as to achieve the purpose of improving its purity and dispersibility
