Refractory organic substances in the environment

Abstract

This book begins with a presentation of the significant progress in isolation and general characterization of refractory organic substances using the ROSIG Priority Program, the analytical methods, mass balance of the isolates, spectroscopic characterization in the UV and Visible range, together with the size-exclusion chromatography. The first part of the book includes the element determination and its quality control in fractions of refractory organic substances and the corresponding original water samples. There are presented some aspects concerning the flame and graphite atomic absorption spectrometry (FAAS, GFAAS), inductively coupled plasma mass spectrometry (ICP-MS), inductively coupled plasma isotope dilution mass spectrometry (ICP-ISMS), instrumental neutron activation analysis (INAA), total reflection X-ray fluorescence spectrometry (TXRF). In the second part are discussed some structural investigations as: - Heavy metal and halogen interactions with fractions of refractory organic substances separated by size-exclusion chromatography; - Characterization of refractory organic substances and their metal species by combined analytical procedures; - Application of nuclear magnetic resonance spectroscopy to structural investigations of refractory organic substances; - Structural characterization of refractory organic substances by solid-state high-resolution 13C and 15N nuclear magnetic resonance; - Quantification of substructures of refractory substances by means of nuclear magnetic resonance; - Nuclear magnetic resonance spectroscopy investigations of silylated refractory organic substances; Book review/Environmental Engineering and Management Journal 3 (2004), 1,75-77 - Isotopic evidence for the origin and formation of refractory organic substances; - Analytical pyrolisis of humic substances and dissolved organic matter in water; - Characterization of refractory organic substances by HPLC/MC; - ...
