Solid-Phase Extraction: Principles and Practice

E. M. THURMAN is an organic geochemist at the U.S. GeologicalSurvey with twenty years of research experience in theenvironmental chemistry of water and soil, as well as extensiveexperience in sorption chromatography and XAD and SPE resintechnology. Dr. Thurman has published research papers on the theoryof XAD resins, applications of SPE in environmental chemistry, drugapplications of SPE, and isolation of natural products by SPE andion exchange. He is the coauthor of Immunochemical Technology forEnvironmental Applications, the coeditor of Herbicide Metabolitesin Surface Water and Groundwater, and has written over 80 journalarticles on environmental analytical chemistry.

M. S. MILLS is a research envi-ronmental chemist with ZenecaAgrochemicals at the Jealott's Hill Research Station, Bracknell,U.K. Dr. Mills was formerly employed by the U.S. Geological Surveyin Lawrence, Kansas, where her research interests includedexploring the mechanisms and applications of solid-phase extractionin environmental chemistry, investigating the organic geochemistryof naturally occurring aquatic foams, and the degradation andtransport of xenobiotics in the vadose zone. She has contributednumerous publications and oral presentations on these topics overthe past five years, and was cofounder and co-lecturer of theAmerican Chemical Society short course, "Solid-Phase Extraction inEnvironmental and Clinical Chemistry." Current research projectfoci include the degradation and transport of xenobiotics in thevadose zone using radiolabeled techniques and the degradation ofxenobiotics in the saturated zone.
