Continuous Liquid-Liquid Extraction of Organic Pesticides from Aqueous Solutions

Abstract: Liquid-liquid extraction (LLE) is considered by most residue analysts to be the best method for quantitative recovery of organic pesticides from aqueous solutions. Continuous liquid-liquid extraction is a logical extension of the process. This paper reviews the LLE process especially the alternative of continuous LLE for the isolation of organic pesticides from aqueous solutions. Trends and user problems are noted. A continuous liquid-liquid extraction apparatus with capabilities for continuous … Show more

“…The aqueous concentrations are shown for the study of: a) the optimization of the continuous liquid-liquid extractor design (using distilled water) and b) recovery studies of natural water under different operational conditions. The gas chromatographic conditions, operational procedures of the extractor, and the water and solvent parameters were previously reported (2).…”
