title: Design and evaluation of a new thermospray liquid/liquid extractor for the extraction of semivolatile and nonvolatile organic compounds from water.
abstract: The recovery of several semivolatile organic compounds (SVOCs) using a new thermospray liquid/liquid extractor (TSLLE) was investigated. The base system includes a 300 mL multiport extraction vessel, jacketed in a 500 mL cooling flask, a dual-stage condenser for progressive cooling, several thermospray probes, and solvent/sample delivery systems. Aqueous mixtures of SVOCs were used to evaluate the TSLLE. For most compounds, recovery values of 80-100% were obtained during a single cycle in <1 h. The design, evaluation, and extraction capability of the TSLLE are discussed.
