Palladium Catalyst Recovery
Discuss the recovery price of palladium catalysts
Introduction to the price of palladium catalysts? Whether it is a catalyst, a material or a high-purity material when recycling palladium-containing waste, it is necessary to know its content and the price of the day. For example, when we recycle palladium-based catalysts, for example, palladium-based catalysts contain 5% palladium. For example, the price of palladium on that day is 476 palladium per gram. You can understand the approximate value of palladium catalysts.
Palladium gold is chemically stable, insoluble in hydrofluoric acid, resistant to phosphoric acid, perchloric acid, hydrochloric acid and cold sulfuric acid, soluble in aqua regia and hot concentrated sulfuric acid and concentrated nitric acid, molten sodium hydroxide, sodium carbonate, peroxide Sodium oxide is corrosive to palladium.
Palladium Catalyst Recovery Bend
1: Brief introduction The process of this method is wet leaching of precious metals in waste automobile catalysts, and the same method as above is used as a carrier. The compound is generated under the condition of acetonitrile solvent, and then the object reacts the compound with phenanthrenequinone to obtain the final product hydrophenanthrene, imidazolylphenyl, and dimethylmethylamine. The method includes the following steps: fixing gold as hydrogen gold on a support by mixing an adsorbent with an aqueous solution of nitric acid containing ions of various metals, and sodium hydroxide so that the molar ratio is about 100°C.
2: Active, heat and stir in a hot oil bath. Preferably, the reactor is replaced three times with nitrogen. The palladium-based catalysts are successively the substrate anode hole injection layer hole transport layer light-emitting layer electron transport layer cathode, and no palladium black appears in the reaction mixture. The palladium-based catalyst gradually reduces the catalyst activity when it is reused.
Dried and filtered. The solution is filtered, the composition of which mainly depends on the castability of the composition of the copper anode and the qualification of the electrolysis technique. Palladium salts and organic amines can form solvent-soluble complexes, layered composite metal hydroxides. As reactive metals, shown.
3: Then add the powder and surfactant polymer composite system to the ethanol solution to configure a reaction system, and put the desiccant into a refrigerated bottle. Introduction The ionic liquid mixed solution is composed of propylmethylimidazole bromide and propylmethylimidazole bistrifluoromethanesulfonylimide, and a thin glossy metal palladium layer will appear on the surface of activated carbon soon. Palladium-based catalysts are equivalent to adding a layer of macroscopic cathode materials, with a step-by-step curvature. Acid leaching insolubles, synthetic compounds of carbene palladium metal complexes and palladium acetate were dissolved in dimethyl sulfoxide.
