Determination of alcohol sulfates and alcohol ethoxysulfates in wastewater samples by liquid chromatography tandem mass spectrometry

► Two methods to quantify alcohol sulfates and alcohol etoxysulfates in wastewaters. ► SPE allows for very low detection and quantification limits. ► Validation of the method: quality parameters, accuracy (trueness and precision). ► Application of the method to samples collected from influents and effluents wastewaters.
