The aim of the work described here was to develop and validate a method by which dibutyl phthalate may be subject to determinations using solid phase extraction and gas chromatography. Optimization of the chromatographic method was based on the selection of working conditions for both the chromatograph and the detector. Following the optimization of extraction and separation parameters, the method was validated by evaluating specificity, the analytical curve, linearity, limits of detection and quantification and recovery. The proposed method has been evaluated in terms of linearity, over a range of concentrations from 0 to 7.5 mg·L-1.The analytical curves show values for correlation coefficients higher than 0.99. Mean recoveries from samples ranged from 97 to 127%, with relative standard deviation lower than 11%. Limit of detection LOD and limit of quantification LOQ values were 0.02 and 0.053 mg·L-1 respectively.
