Extraction Techniques in Analytical Sciences

Increasing environmental regulations have resulted in the need for new methods of analysis for environmental samples. As an updated version to Extraction Methods for Environmental Analysis published in 1998, Extraction Techniques in Analytical Science provides the fundamentals of extraction methods in environmental organic contaminants. The text explores topics like aqueous samples, solid samples, gaseous samples, comparisons of extraction methods, and resources. Also, the book discusses methods of analysis, including chromatographic approaches for environmental organic analysis. Written in the AnTS style, this text is ideal for students as a self-study guide.

About the Author :
John R. Dean took his first degree in Chemistry at the University of Manchester Institute of Science and Technology (UMIST), followed by an M.Sc. in Analytical Chemistry and Instrumentation at Loughborough University of Technology, and finally a Ph.D. and D.I.C. in Physical Chemistry at the Imperial College of Science and Technology (University of London). He then spent two years as a postdoctoral research fellow at the Food Science Laboratory of the Ministry of Agriculture, Fisheries and Food in Norwich, in conjunction with the Polytechnic of the South West in Plymouth (now the University of Plymouth). His work there was focused on the development of directly coupled high performance liquid chromatography and inductively coupled plasma-mass spectrometry methods for trace element speciation in foodstuffs. This was followed by a temporary lectureship in Inorganic Chemistry at Huddersfield Polytechnic (now the University of Huddersfield). In 1988, he was appointed to a lectureship in Inorganic/Analytical Chemistry at Newcastle Polytechnic (now Northumbria University). This was followed by promotion to Senior Lecturer (1990), Reader (1994), Principal Lecturer (1998) and Associate Dean (Research) (2004). He was also awarded a personal chair in 2004. In 2008 he became the Director of The Graduate School at Northumbria University as well as Professor of Analytical and Environmental Sciences in the School of Applied Sciences. In 1998, he was awarded a D.Sc. (University of London) in Analytical and Environmental Science and was the recipient of the 23rd Society for Analytical Chemistry (SAC) Silver Medal in 1995. He has published extensively in analytical and environmental science. He is an active member of The Royal Society of Chemistry (RSC) Analytical Division, having served as a member of the Atomic Spectroscopy Group for 15 years (10 as Honorary Secretary) as well as a Past Chairman (1997-1999). He has served on the RSC Analytical Division Council for three terms and is a former Vice-President (2002-2004), as well as a past-Chairman of the North-East Region of the RSC (2001-2003).
