Abstract

The invention relates to the field of miniature extraction devices, in particular to a miniature extraction device based on a hollow foam material and application thereof. A main function component ofthe miniature extraction device is composed of the hollow foam material formed by macroscopically three-dimensionally communicated frames; the network frames are three-dimensionally communicated hollow microchannels; the walls of the microchannels include nano to micro sized pores. The hollow foam miniature extraction device with three-dimensionally communicated network is prepared via the structural design of the miniature extraction device. The hollow foam miniature extraction device has the advantages that the walls of the three-dimensionally communicated hollow microchannels include richpores inside, chances for an extracting agent to contact a solution to be extracted during extraction can be increased, the miniature extraction device is suitable for modular assembly, has good convenience of automatic running and has a clean and efficient extraction process.

Description

technical field [0001] The invention relates to the field of micro-extraction devices, in particular to a micro-extraction device based on a hollow foam material and its application. Background technique [0002] Extraction technology is a method of separation using the difference in the distribution behavior of components between two immiscible solvents. It has been widely used in hydrometallurgy, chemical production, biochemical engineering, pharmaceutical engineering and other fields. However, the traditional extraction technology has many disadvantages, such as volatile organic solvents and harmful to human body, cumbersome and time-consuming manual operation, low separation efficiency, and many separation stages. Therefore, the development and application of efficient and green extraction technology has gradually become a research hotspot. [0003] In the actual production process, the micro-extraction device has been widely concerned due to its advantages such as high...
