Features: Due to the characteristics of environmental samples, such as low measured concentrations, complex components, numerous interfering substances, the existence of the same element in multiple phases, and susceptibility to environmental influences, they typically require complex pretreatment before analysis and measurement. This book systematically introduces various advanced sample pretreatment technologies currently used internationally. The book is divided into twelve chapters, covering new technologies such as solid-phase extraction, solid-phase microextraction, microwave extraction, supercritical fluid extraction, immunoaffinity, purge and trap, and continuous-flow liquid membrane extraction, along with their development status. It also discusses the pretreatment methods for typical toxic chemical pollutants, such as dioxins, polychlorinated biphenyls, and organometallic compounds, providing numerous application examples. This book can serve as a training textbook for environmental sample analysts and is also suitable for students and teachers in higher education institutions majoring in related fields, as well as analytical technicians in other industries for reference.
