## Abstract Solid‐phase extraction combined with dispersive liquid–liquid microextraction (SPE‐DLLME) was applied for the extraction of six organophosphorous pesticides (OPPs) in water samples. The analytes considered in this study were determined by gas chromatography with mass spectrometry and in
## Abstract For the first time a dispersive liquid–liquid microextraction method on the basis of an extraction solvent lighter than water was presented in this study. Three organophosphorus pesticides (OPPs) were selected as model compounds and the proposed method was carried out for their preconce
## Abstract In this study, the organochlorine pesticides (OCPs) levels in lake and tap water samples were determined by a dispersive liquid–liquid microextraction method using a low‐density organic solvent and an improved solvent collection system (DLLME‐ISCS). This method used a very small volume
