Liquid-liquid extraction for neutral, acidic and basic compounds
Liquid–liquid extraction is the classical method used for herbicide isolation, especially from water and biological fluid samples. Ethyl acetate, dichloromethane, and their mixtures are among the preferred extraction solvents for phenylureas, triazoles, amides, carbamates, benzimidazoles, and chlorotriazines. The extraction efficiency…
Extractions are among the most widely used methods in analysis to separate mixtures. They are based on the difference in affinity of a solute between two mutually immiscible phases. We give here the principle of the liquid-liquid extraction which makes…
