Key words: supercritical fluid extraction, supercritical CO2, human hair, chloro-organic pesticides, phosphoro-organic pesticides, GC-MS
A supercritical fluid extraction process using supercritical carbon dioxide for isolation of chloro-organic and phosphoro-organic pesticides in the human hair is developed. The effect of process parameters (temperature, pressure, duration) on the efficiency of pesticide extraction is studied. Gas chromatography-mass spectrometry technique is used for quantitative analysis of pesticide concentration.
