In this study a new version of solid phase extraction performed in a narrow–bore tube using large volume of sample followed by dispersive liquid–liquid microextraction has been proposed to achieve a high sensitive analytical method. It has been used for the extraction and preconcentration of trace concentrations of some pesticides (metalaxyl, haloxyfop–r–methyl, clodinafop–propargyl, diclofop–methyl,...
