Abstract
A reversed phase LC-FTIR interface is described using on-line extraction of the aqueous effluent with a volatile organic solvent in conjunction with a solvent eliminating spray-jet device. Results are shown of the analysis of a 2. 10-4 M solution of acenaphthenequinone, phenanthrenequinone and two polar pesticides linuron and diuron. The mixture was separated with a mobile phase of acetonitrile-phosphate buffer and post-column extracted with dichloro-methane. Detection was carried out by FTIR transmission microscopy. The characteristics of the on-line extraction system are discussed in relation to results obtained from a direct deposition method.
