Iridium-containing catalysts have a wide range of applications in the industrial field, especially in petroleum refining, chemical synthesis and environmental protection. Iridium's unique chemical properties, such as its high melting point and excellent chemical stability, make it an indispensable catalyst component in these fields.
The refining and refining of iridium requires a series of complex chemical and physical processes. This typically includes catalyst pretreatment, chemical dissolution, iridium extraction, and purification steps. Pretreatment involves crushing and separating the catalyst for more efficient chemical treatment. Subsequently, iridium is extracted from the catalyst by methods such as chemical solvents or pickling, and finally purified by chemical precipitation, ion exchange, or electrochemical methods.
The sampling step is considered to be the most important part of this process. The reason is that the ** value of iridium - the ** of iridium can be as high as 850 yuan a gram. If there is an error in the sampling step, such as insufficient sample representativeness or inaccurate content determination, it will directly affect the efficiency and economic value of the entire process, resulting in millions of losses. An inaccurate sample can lead to a misjudgment of the iridium content in the catalyst, which can lead to wasted resources and financial losses during extraction and purification.
Therefore, ensuring the accuracy of sampling is not only a technical requirement, but also a guarantee of economic benefits. Specialized sampling methods must ensure the homogeneity and representativeness of the sample, using precise chemical analysis techniques such as mass spectrometry or atomic absorption spectrometry to determine the exact amount of iridium in the sample.
