DEVELOPMENT OF A BINARY SOLID-PHASE EXTRACTION CARTRIDGE FOR USE IN SCREENING WATER SAMPLES FOR ORGANIC POLLUTANTS

摘要

Two chemically modified resins and a range of commercially available material were evaluated for use as solid-phase sorbents in an analytical procedure designed to screen water samples for trace level organic contamination. A binary cartridge, comprising acetyl-derivatised resin and an anion-exchange phase, was found to perform better for most compounds than conventional liquid-liquid extraction using dichloromethane.
