2.3: LIQUID-LIQUID EXTRACTION - Chemistry LibreTexts
2021年6月20日 · Liquid-liquid extraction involves the exchange of certain com- pounds between two solvents that are immiscible or only partially miscible. Liquid-liquid extraction is also very commonly used for washing an organic phase, for example to remove inorganic compounds, or to protonate or deprotonate bases or acids, respectively, so they become ...
Liquid–liquid extraction - Wikipedia
Liquid–liquid extraction, also known as solvent extraction and partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (non-polar).
