Alumina Palladium Recovery
Determination of how much is recovered per kilogram of alumina palladium
Understand how much is alumina palladium per kilogram? When recycling palladium-containing waste, whether it is equipment, materials or plating materials, it is necessary to know its content and current price first. For example, when we recycle alumina palladium, for example, there is 5% palladium in alumina palladium. For example, the current price of palladium is 442 palladium per gram. Then you can know the preliminary price of alumina palladium.
Platinum group metals (PGM) such as Pt and Pd have very high melting temperature and good corrosion resistance to chemical corrosion. In addition, PGM also has unique chemical characteristics such as reduction catalysis. Therefore, it is widely used in petrochemical, aerospace, electronics, atomic energy, experimental instruments, medicine and other fields. In particular, noble metal-containing catalysts are widely used in petrochemical fields due to their excellent catalytic activity. Such catalyst products typically lose activity over time and become spent catalysts containing precious metals. Therefore, recycling of platinum group metals is economically advantageous, and resources can be effectively used.
Alumina Palladium Recovery Index
1: Understand that a solution of an organometallic palladium compound is used instead of an aqueous solution dissolved in palladium, and a large amount of hydrogen sulfide gas is released. Every liter is about to mol in the phase bath of a few selected substances, and the alkaline substance used to adjust the surface value of the catalyst during the treatment process is sodium hydrogen potassium hydroxide or sodium carbonate potassium carbonate or sodium bicarbonate to adjust the surface value to above. The alloy is formed from crystalline nanoparticles, an indicator of organic phase mixing.
2: Add ethyl xanthate, international version. Copper ions were added last and were found to etch gold and palladium in seconds. Alumina palladium sucks and collects filtrate, and the content of platinum, palladium, rhodium and iron in the hydrolyzate is all below. Alumina Palladium Turn to the drawings for a more detailed explanation of the apparatus, but the invention is not limited to the process details described above.
Iron single metal and nano-iron bimetal, take out and grind into powder. Dissolving the intermediate prepared in the step and iridium trichloride hydrate in an organic solvent, and synthesizing polyhedral nanomaterials under the temperature conditions of the next step. It has excellent characteristics such as high catalytic activity and good selectivity, and a suitable example is the complex of palladium amine and chloride, bromide, nitrite and sulfite. Temperature, remove impurities in the solution with cationic resin.
3: Carry out matrix dissolution reaction, mix the above compound with a solution of simulated palladium ions. It is understood that changing the nickel-gold plate is only suitable for surface treatment with a line distance above wide, and the invention of adding activated carbon. Aluminum oxide palladium removes substances on the palladium-containing titanium oxide layer, and is easy to separate from organic substances. Solder metals containing nickel-palladium alloys have been developed with palladium concentrations of .
The above is the full text of alumina palladium recycling, I hope it will be helpful to everyone!
