| Abstract: | This paper studies on liquid-liquid extraction process of 14 kinds of phenolic compounds in water, and optimizes the parameters such as different extraction solvent system, sample pH and salting-out condition which making decisive influences on the extraction efficiency. Through Optimization, we realize the synchronous extraction of phenols, including chlorinated phenols of low boiling point, and difficultly extracted phenols such as methyl phenol and nitro-phenol.The extraction efficiency of 14 different types of phenolic compounds in water is up to 75.2%-110.3%. |
