文摘

A supramolecular solvent (SUPRAS) made up of aggregates of gemini surfactant was introduced. A microextraction method, based on the SUPRAS was applied for extraction of parabens. Separation and determination of the parabens was performed by HPLC-UV. Parameters affecting extraction of the analytes were optimized by one variable at a time method. Under the optimal conditions, the preconcentration factors in the range of 98–156 were obtained.
