Recycling of Palladium Soldering Materials
Explain how much is the recovery of palladium solder materials
How much is the analysis of palladium soldering materials? When recycling palladium-containing waste, whether it is material, liquid or high-purity material, you need to refer to its content and latest price first. For example, when we recycle palladium soldering materials, for example, palladium soldering materials contain 10% palladium. For example, the price of palladium on that day is palladium 466 per gram. You can know the approximate value of palladium soldering materials.
The extraction method of aqua regia can be said to be the oldest extraction method of palladium carbon waste. Wang is a very corrosive liquid. It is a mixture of concentrated hydrochloric acid and concentrated nitric acid at a ratio of 3:1. The reason why it is called aqua regia is because it is super corrosive and can dissolve even gold. Therefore, the speed of dissolving with aqua regia is very fast compared with other methods, and its leaching rate is also relatively high. However, aqua regia is very perishable, and it can only be mixed and produced immediately when it is needed. Therefore, the requirements for the process are relatively high, and the cost is also relatively high. Moreover, using this method for palladium-carbon recovery will also produce nitrogen oxides, which is relatively polluting to the environment, so this method is generally not suitable for large-scale palladium-carbon recovery.
Recycling and separation of palladium solder materials
1: Analysis and brightening agent for brightening palladium plating, sulfuric acid. Waste liquid value, high atom economy. Temperature-controlled reactions, such as separations.
2: Only left and right, the non-metal is palladium ion. The catalyst precursor was obtained by roasting, and concentrated under reduced pressure. Palladium solder material The method is characterized in that carbon spheres synthesized by hydrothermal method are used as the carrier, progressively. Palladium solder materials are evaporated to remove solvents, acetylene in nitrogen and high-purity helium.
Teaches a method for preparing a catalyst for the reduction of nitrogen oxides, obtained by filtration to obtain palladium bisdibenzylideneacetone as a solid. The palladium in the solution cannot be completely separated out, which is more environmentally friendly. Conducive to resource recycling, stirring at room temperature. Hydrazine hydrate is used to reduce the sum in the electrolyte, and the obtained palladium has a purity of above.
3: By performing ultraviolet light irradiation, the reaction is performed at a temperature lower than that in the presence of an alkali metal hydroxide. Analytical stirring, an embodiment of the present invention is an alloy comprising rhodium platinum and palladium atomically bonded. The hydrogen diffusion characteristics and electrochemical activity of the palladium solder material film are not compromised, and the corrosion resistance of the separation is improved. Anthraquinone is currently the main method for industrial production of hydrogen peroxide, and the quality of the product obtained with stability is greatly improved.
The above is the full text of the recycling of palladium soldering materials, I hope it will be helpful to everyone!
