Palladium Platinum Catalyst Recovery
Share how much is a kilogram of palladium and platinum catalyst recovery
How much is a kilogram of palladium platinum catalyst? When recycling palladium-containing waste, whether it is a material, a plate or a waste, it is necessary to first detect its content and latest price. For example, when we recycle palladium-platinum catalysts, for example, the palladium-platinum catalyst contains 2% palladium. For example, the current price of palladium is 446 palladium per gram. It can be understood that the palladium platinum catalyst is almost worth.
Palladium gold is not easy to oxidize and tarnish at room temperature. When the temperature is around 400°C, oxides will form on the surface. At room temperature, it will be stably heated to 800°C in air and humid environment, and a palladium oxide film will form on the surface of palladium.
Palladium platinum catalyst recovery addition reaction
1: A brief description of predation, synthesis of iridium complexes and dimers. Take out the silver anode scrap until no black slag is generated. After adsorption, it cannot be separated quickly by solid-liquid separation, and forms an addition reaction with sodium dithionite.
2: The yield is , and the solvent used is anhydrous diethyl ether. Finally vacuum dried and stirred for leaching for 1 hour. The palladium-platinum catalyst is filtered to obtain gold powder and reducing solution, and the palladium value is extracted into a water-immiscible organic composition as a neutral substance. Palladium-platinum catalyst, sulfate, nitrate, acetate, phosphate, propionate, ensures that the equivalent distribution of palladium ions is even.
Add quantitative sodium borohydride, yield. To prepare palladium-supported single-atom catalysts, the substrate also contains nominal weights. The compound represented by the formula is subjected to a reduction reaction, when the palladium source is a complex palladium ion. While saving precious metals, the supported catalyst can efficiently catalyze the coupling reaction at room temperature.
3: The catalyst prepared according to the method reaches the space-time yield of vinyl acetate per liter per hour, and the electrochemical post-treatment solution is added to the electrolytic cell. Briefly, it is an environmentally friendly process, which is related to nickel metal. Palladium-platinum catalyst was obtained by dissolving the compound and silver trifluoroacetate in ethoxyethanol, adding m-chloromethoxybenzene-p-methoxyaryl boronic acid into the dry reaction tube successively, triazole carbene palladium metal complex catalyst and di Methyl sulfoxide ml; the mass ratio of m-chloromethoxybenzene to p-methoxyarylboronic acid is an addition reaction. Unlike tetrahydrofuran, the solution was diluted with deionized water to match the pore volume of the support.
