Abstract: The aim of this paper is to present the characteristics of solid phase extraction for environmental analysis using liquid matrices or extracts. The basic principles controlling the extraction are presented in order to aid in the choice of the nature and quantity of the extracting phase according to the sample matrix and the solute properties., based oil the mechanisms of phase retention. Recent developments in available formats, types of phases and automation are considered. Special emphasis is placed on emerging selective phases, in particular those. such as immunoabsorbants molecularly imprinted polymers, which function via molecular recognition and allow selective extraction in a single step. Performance in on-line coupling with liquid phase chromatography is illustrated by examples from environmental analysis. Some examples specific to analysis of petroleum products are also presented
