摘要：

A general system for the extraction and concentration of organic compounds based on a closed-circuit extraction/back-extraction procedure and real-time spectrophotometric monitoring by use of a diode-array detector is reported. Application of multi-component analysis techniques allows the changes in each mixture component to be distinguished and the components to be determined. The proposed system was used to analyse various mixtures of phenol compounds.
