PRECONCENTRATION AND DETERMINATION OF SHORT CHAIN MERCAPTANS IN THE PRODUCED WATER BY DISPERSIVE LIQUID-LIQUID MICROEXTRACTION AND GAS CHROMATOGRAPHY

This paper describes the preconcentration of short chain n-alkyl C1-C6 mercaptans in the produced water using the dispersive liquid-liquid microextraction. In the present experiments, 0.8 mL dispersive solvent (acetonitrile) containing 10.0 µL extraction solvent (carbon tetrachloride) was rapidly in...
