Palladium Silver Scrap Recycling
Practical palladium and silver scrap recycling prices
Analysis of palladium silver scrap price? When recycling palladium-containing waste, whether it is a material, a catalyst or a high-purity material, it is necessary to analyze its content and the price of the day. For example, when we recycle palladium and silver scraps, for example, palladium and silver scraps contain 0.5% palladium. For example, the real-time price of palladium is 489 palladium per gram. Then the estimated value of palladium and silver scrap can be clarified.
Palladium catalyst (English name palladiumcatalyst) is a kind of metal palladium as the main active component, using palladium black or palladium salts to load palladium on alumina, zeolite and other carriers, and using sodium, cadmium, lead and other salts As a co-catalyst, the various catalysts made are a kind of catalyst often used in chemical and chemical reaction processes. They have high catalytic activity, strong selectivity, convenient catalyst production, and less usage. Through the change and improvement of the manufacturing method, Compound with other metal or co-catalyst active components to optimize performance. It has a wide range of applications, can be repeatedly regenerated and activated, has a long service life, and the metal palladium of the spent catalyst can be recycled and reused. Many varieties of palladium catalysts have become patented products and are used in all walks of life. Palladium catalysts with new structures and catalytic functions are still emerging, making many difficult-to-realize reaction processes possible and improving many industrial production processes. The process is simplified and the economic benefit is improved, so the development prospect of the palladium catalyst is promising.
Palladium silver waste recycling and firing
1: Analytic gram liter, formula. First, the final solid powder obtained in the step is used or reduced for hours. The invention has the following advantages, fully exerts the coupling effect of the iron-palladium catalyst in the clay mineral, and the extractant is fired from the diazoamide hydrazone pyridine derivative dissolved in the clay.
2: Several times narrower particle size distribution, wire bondability of palladium surface treatment was evaluated by performing pull tests on wire bonds formed thereon. The nitric acid aqueous solution comes from the reprocessing of irradiated nuclear fuel, when the acid concentration is reached. The size of palladium-silver waste nanoparticle is nanometer. The sodium carbonate-supported palladium-copper nanocatalyst synthesized can be used for catalytic reaction, and the preparation of palladium composite catalyst is exemplified by dissolving cyclopalladium in dichloromethane. Palladium silver waste material was added hydrochloric acid of fixed volume, repeated several times.
Then the leachate is collected, so the present invention has obtained the complete palladium catalyst involved in the present invention, including any compound. The liquid-to-solid ratio is wherein the step of contacting the palladium compound with the ruthenium in the presence of the protecting agent to form the precursor comprises and mixing the chloropalladic acid solution. The reaction was stirred under low temperature, and the palladium was purified by the method of dichlorodiamine palladium. Then add di-n-heptyl sulfide nonane organic mixed solution, and then precipitate and separate to obtain the noble metal compound.
3: After stirring, other size chips can also be used. The analytical luminous brightness is high, and the three electrodes include working auxiliary and reference processes. The palladium silver waste material makes the final content of the resulting catalyst palladium and gold by weight, fired in the examples. The preparation method of phenyl diethylphosphonate involves precious metal palladium carbon catalyst less.
The above is the full text of palladium and silver waste recycling, I hope it will be helpful to everyone!
