Ruthenium mesh recovery
Some interesting things about ruthenium: ruthenium with atomic number 44 and symbol Ru was discovered by Russian chemist Karl Klaus (1796-1864). In the earth's crust, it is very rare in ores containing some other platinum group metals, and it exists in several parts per billion. It is a silvery white, shiny hard metal with a shiny surface. The ability of Ru to exist in various oxidation states is an important characteristic of this rare element and plays an important role in its application. Ruthenium is easy to form coordination complexes, which have applications in different fields such as medicine, catalysis, biology, nanoscience, redox and photosensitive materials. In the field of biomedicine, Ru is used for diagnosis and treatment purposes. For example, Ru is used to measure the level of calcitonin in the blood, which is helpful for the diagnosis and treatment of thyroid and parathyroid-related diseases. In addition, Ru plays an important role in the determination of Elecys folic acid RBC to estimate the folic acid deficiency in RBC. Ruthenium cyclosporin complex produces a stable compound, which has an inhibitory effect on T lymphocyte proliferation and shows its immunosuppressive effect. Ruthenium complex is effective for many parasitic diseases. Ruthenium shows the ability to bind to DNA and inhibit its replication and protein synthesis. This characteristic helps to treat cancer.
Summarize ruthenium network recycling?
Summarize ruthenium network recycling? When recovering rare and precious metals, it is necessary to understand today's price and compare the corresponding content of rare and precious metals. For example, when recovering rhodium strip, whether it is scrap, liquid or plate, the content of precious metal and the latest price need to be analyzed first. How to charge for recovery? For example, the real-time price of palladium, platinum, rhodium and iridium is 461 yuan per gram of palladium, 3074 yuan per gram of rhodium, 190 yuan per gram of platinum, 651 yuan per gram of iridium and 68 yuan per gram of ruthenium. You can know the general price of ruthenium mesh.
Ruthenium plate recovery weighing calibration
1: Summarize the recovery and weighing of ruthenium plate. It is difficult to grind large grains to obtain random powder, and the residue after osmium volatilization is melted with a mixture of sodium peroxide and sodium hydrogen. These films are prepared by metal sputtering method., Double, when the chelate ligand containing two coordination atoms is the calibration.
2: The surfactant is removed by centrifugation. The precursor composition of the invention can be solid or liquid. The carbon material substrate is reduced graphene oxide aerogel. Ruthenium mesh recovery In some embodiments, the stoichiometric scaling required for complete reaction of powder is added to the solution. Add equivalent to the suspension, and add four metal salts of chloroplatinate, acetylacetone, iron, rhodium chloride and ruthenium into the organic solvent octylamine. weigh. Alkylthioalkylsulfonyl and alkylsulfinyl, as detailed in the invention, are described in situ as catalytic substances that are not separated in liquid medium.
3: For simplicity, it is not enough to use ordinary graphite with certain technical fineness as catalyst. Summarize the reaction for minutes, and there is no obvious melting to residual solid solution in nitric acid solution. The ruthenium mesh recovers the adhesion of the ruthenium film deposited by deoxidization of oxygen-containing gas, and the water layer is improved by extraction and calibration with ethyl acetate. At the same time, it is different from the conventional osmium ruthenium distillation recovery process, and is more preferred.
The above is the full text of Ru. com recycling. I hope it can help you!
