Oxidation state properties of ruthenium
Ruthenium exists in various oxidation states, the most common of which are +4 and +3. Oxides of ruthenium, such as RuO2 (Ruthenium dioxide), exhibit a high degree of stability and good electrical conductivity, making them indispensable materials in electrolytic capacitors and other electronic components. In addition, the oxidation state of ruthenium is particularly effective for catalytic reactions, especially for oxidation reactions and hydrolysis reactions in the chemical industry.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47942.html

Collecting ruthenium-containing waste: First, you need to collect ruthenium-containing waste, which can come from discarded electronic equipment, catalysts, or byproducts of chemical production processes.
Pretreatment and sorting: The collected waste is pretreated, such as crushing and sorting, to remove impurities and sort.
Chemical leaching: The pre-treated material is treated by chemical leaching, which uses a strong acid (such as hydrochloric or sulfuric acid) to dissolve ruthenium oxide and convert it into ruthenium ions in solution.
Extraction and purification of ruthenium: Extraction of ruthenium ions from solution, common methods include solvent extraction and ion exchange. This step is designed to separate ruthenium and other metal ions to obtain high purity ruthenium.
Reduction of ruthenium: Finally, ruthenium ions are reduced to metallic ruthenium by a chemical reduction process. This can be done by adding a reducing agent, such as hydrogen or methanol, under specific conditions.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47942.html
