Development of a Teflon Helix Continuous Liquid-Liquid Extraction Apparatus and Its Application for the Analysis of Organic Pollutants in Drinking Water

Source

A continuous liquid-liquid extractor (CLLE) applicable for isolation and enrichment of trace organic constituents found in drinking water is described. The CLLE is automated for unattended operation and accomplishes the mixing, separation, and solvent recovery operations sequentially. Solvent recycle is employed to minimize solvent usage. The optimization procedures and evaluative criteria for the CLLE are presented along with two specific examples of drinking water applications.

The variability of the final evaporation step for highly volatile organics limits the use of this system for quantification of “low boilers”; however, purge and trap analyses can be utilized to quantify these compounds.
