About this work
In this study switchable solvent liquid phase microextraction (SSLPME) followed by GC-MS detection has been developed for preconcentration and determination of total petroleum hydrocarbons (TPHs) in water samples. The extraction technique makes use of 100 μL of a water-immiscible solvent (dipropylamine) that can be solubilized in the aqueous phase in 1:1 ratio using HCl as a reagent. Afterwards, phases separation is induced by the addition of sodium hydroxide. Optimization of the variables af...
