The method of separating substances by utilizing their different solubility in two immiscible solvents is called extraction. The commonly used traditional extraction methods currently have many shortcomings, such as requiring a large amount of reagents, high experimental costs, complex sample processing steps, waste of time, manpower, unsatisfactory sample recovery rate, precision, and easy sample loss. With the emergence of problems, corresponding solutions have emerged: new technologies such as solid-phase extraction, solid-phase microextraction, supercritical extraction, and microwave extraction have emerged.
Several Types of Extraction Technology
1. Organic solvent extraction
2. Aqueous two-phase extraction
3. Supercritical extraction
4. Microwave extraction
5. Ultrasonic extraction
6. Ultra high pressure extraction, etc
