What is the rhodium content in the catalytic converter, and the refining method of metal rhodium.

The catalytic converter is an indispensable part of the modern automobile exhaust gas purification system, and its core role is to convert harmful gases emitted by automobiles into relatively harmless substances to the environment. In this process, rhodium, as a precious catalyst material, plays a crucial role. So, how much rhodium is in the catalytic converter, and how is this rare metal extracted?

Rhodium content in catalytic converters
Inside the catalytic converter is a complex catalyst that includes not only rhodium, but also precious metals such as palladium and platinum. The specific amount of rhodium in the catalyst varies depending on the manufacturer and the design of the catalytic converter, but in general the amount of rhodium is less than that of palladium and platinum. In a typical automotive catalytic converter, the rhodium content may be only 1% to 5% of the total precious metal. Although the proportion is not high, the presence of rhodium is crucial for catalytic conversion of harmful gases, especially in reducing nitrogen oxides (NOx) in vehicle exhaust.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48432.html

Refining method of metal rhodium
Rhodium extraction is a complex and technically demanding process. Rhodium usually occurs in nature with other platinum group metals, so refining first requires extracting rhodium-containing raw materials from ores. The steps for refining rhodium usually include:文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48432.html

Pretreatment: The rhodium-containing ore is crushed and then the rhodium-containing substance is separated from the ore by thermal or chemical methods.
Dissolution: The extracted substance is dissolved in a mixed acid (usually aqua regia) to form a rhodium-containing solution.
Chemical treatment: Through a series of chemical reactions, such as precipitation, filtration and extraction, further purification and removal of other metal impurities.
Electrolytic purification: Finally through the electrolytic process, high purity rhodium metal is deposited from the solution.
This complex series of extraction steps requires a high degree of technical expertise and sophisticated equipment, so rhodium is relatively expensive to extract.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48432.html
