The invention relates to an analytical method for determining phthalate in milk samples. According to the invention, the method consists of the milk sample extraction with ultrasounds, by using a mixture of cyclohexane : dichloromethane solvents, at the environmental temperature, for 15...30 min, followed by the extract evaporation, then by the lipide acid destruction, the micro-extraction in the solid phase of the analytes and the simultaneous determination of the 6 phthalic esters by gas chromatography coupled with mass spectrometry. |
