Headspace microdrop liquid-phase microextraction (LPME) using ionic liquids as extracting solvents, followed by gas chromatography–electron capture detection was successfully developed to determine organochlorine pesticides in soil samples. A feature of the developed procedure is the simple handling of the ionic liquid extract in a normal, unmodified gas chromatograph injection port such that no special...
With the increasing concern over deteriorating environmental quality, the analysis of organic pollutants in air, water, and soil has become critically important. The development of simple, efficient, and inexpensive analytical sample pretreatment is crucial for monitoring and evaluating the environment. In this work, a dynamic hollow-fiber supported headspace liquid-phase microextraction (DHF-HS-LPME)...
