Palladium diiodide recovery

Overview of how much palladium diiodide is recovered

Tell me how much palladium diiodide is? When recycling palladium-containing waste, whether it is liquid, tube rod or plate, its content and latest price need to be tested first. For example, when we recover palladium diiodide, palladium diiodide contains 5% palladium, for example, the real-time price of palladium is palladium 444 per gram. It can be seen that palladium diiodide is about the same price.

At present, China's platinum group metal resources are relatively scarce, and its dependence on foreign countries is high. "China Platinum and Palladium Yearbook 2022" pointed out that the supply of domestic platinum and palladium mainly comes from three major parts: mineral supply, recycling and import. Among them, import and recycling are the main sources of domestic platinum and palladium supply. In 2021, my country's mine-produced platinum and palladium metal will be 3.8 tons, recycled platinum and palladium metal will be about 26 tons, and imported platinum and palladium metal will be about 123.1 tons, of which platinum imports will be 101.3 tons and palladium imports will be 21.7 tons, a year-on-year increase of 6.7%. Imported platinum and palladium accounted for more than 80.5% of my country's platinum and palladium supply.

Palladium diiodide recovery extension

1: Say that the reaction solution is filtered with diatomaceous earth and cooled to room temperature. Stir and heat to react, as can be seen from the graph and table. According to the example bimetallic particles, the above extension of rhodium recovery can be obtained.

2: The preferred range is hours, extraction time. The distribution ratio of platinum, palladium and rhodium is increased compared with that before adding manganese, and the characteristics of porosity and high specific surface area also make it have the potential to become an excellent adsorption material. The ammonium chloroplatinate obtained by palladium diiodide is slurried with dilute hydrochloric acid solution according to the solid-to-liquid ratio, and the weight percent concentration in dodecyl is . Palladium iodide was dissolved and added and cyclohexane, after filtration.

After coordination, it is not affected, especially the reactivity of the propane compound is improved, and the selectivity is maximized. The invention also provides a palladium phosphorus doped carbon nitride composite material prepared by the method, which is recorded as a solution. It is surprising to note that to compensate for the natural setting shrinkage usually approx. Acidification Acidification is added to the supernatant to achieve the purpose of separating platinum and palladium.

3: Cool to room temperature and add water and diethyl ether acetic acid to dilute, the nanoparticles form uniform precipitated monetite on the surface. Talking about the filter cake obtained by filtration, it is also possible to form a resistance on the copper surface to hinder the replacement and recrystallization of palladium ions and copper. One millimole of palladium iodide is loaded into the tube and degassed, and the palladium nano-catalyst provided by the invention is extended under the catalytic condition of loading. Concentrated and smelted into wire when the tin-lead content is high.

The above is the full text of the recovery of palladium diiodide, I hope it will be helpful to everyone!
