Palladium(II) Chloride Recycling

Palladium salts typically exhibit white or yellow crystals with good solubility. Its melting point is relatively high, about 1554 ℃, and its density is 11.99 g/cm ³。 Palladium salts have good conductivity and thermal conductivity, making them an excellent catalyst material. Palladium salts are relatively stable in air, but are easily oxidized by oxidants such as nitric acid. It can form compounds with many non-metallic elements, such as Palladium(II) sulfide and Palladium(II) chloride. Palladium salts are usually divalent, and their Oxidation state can be+2 or+4.

The recovery process leverages autoclave conditions to effectively extract palladium, with considerations for scale, efficiency, and environmental impact. Understanding the exact chemical reactions and conditions within the autoclave, as well as the comparative effectiveness of different recovery methods, is vital for optimizing palladium recovery and its industrial applications.

Palladium alumina is a catalytic material composed of palladium (Pd) supported on an alumina (Al₂O₃) carrier, usually in the form of highly dispersed metal palladium nanoparticles.Its composition includes:
Active metal: palladium (Pd), usually accounting for 0.1% to 10% (mass fraction)
Carrier: alumina (Al₂O₃), providing high specific surface area and stability
Additives (optional): such as rare earth metals or alkali metals, which can optimize catalytic activity.

A palladium catalyst is a chemical catalyst that uses palladium (Pd) as its active component, typically supported on materials such as alumina, activated carbon, silica, or zeolite. It is widely used in various industries due to its excellent catalytic properties.Recycling methods include acid leaching, solvent extraction, high-temperature smelting, and electrolysis, which allow for the recovery and refining of palladium to a purity of 99.95% or higher.
