The method of separation based on the different solubility of substances in two immiscible solvents is called extraction. At present, the traditional extraction methods commonly used have many shortcomings, such as the need for a large number of reagents, high test costs, complex sample processing steps, waste of time, manpower, sample recovery, precision is not ideal, and sample loss. With the emergence of the problem, there are also corresponding solutions to the problem: solid phase extraction, solid phase microextraction, supercritical extraction, microwave extraction and other new technologies emerged as the times require.
