Abstract: Recently, the solid phase extraction technology has received considerable attention considering serious environmental problems and much more contaminants present in the samples at trace level that is different to be analyzed. During the whole process of analyzing sample, the preconcentration of sample is the most complicated and significant step, which typically spend much time, affecting the analysis efficiency and accuracy of results to a large extent. Obviously, the sample pretreatment has become an obstacle that prevents us from improving analysis efficiency. If this problem cannot be resolved, the overall efficiency of analytical work will not be enhanced, even using the advanced analysis devices. As a result, increasing the success rate of sample pretreatment is especially necessary. Now, this review mainly represents the current development of solid phase extraction from the following aspects: (1) the type of adsorbent, including organic, polymer materials; (2) the different mode of separation, such as solid phase extraction, molecule imprinting solid phase extraction, solid phase microextraction, dispersive solid phase extraction, matrix solid phase dispersion, magnetic solid phase extraction, microchip solid phase extraction, stir bar sorptive extraction, immunoaffinity solid phase extraction, monolith solid phase extraction; (3) the practical applications of various solid phase extraction methods are also have been described in this article.
