Problems solved by technology

[0005] In order to solve the problem in the background technology that there is currently no device capable of using in-situ QXAFS technology for real-time analysis and research on the dynamic process of heavy metal adsorption by materials in a solution system, it is impossible to realize real-time research and analysis on the dynamic process of heavy metal adsorption by materials, and then It is difficult to effectively explore the adsorption mechanism of heavy metals in the initial process of adsorption, which will eventually affect the research and development of adsorption materials for the efficient removal of heavy metals in water. To provide a test device for in situ research on the dynamic adsorption reaction of heavy metals in water, it can use in situ synchrotron radiation Study on dynamic adsorption process of heavy metals in solution by QXAFS method
