  • Description
  • Contents

As biomaterials that are of vital importance to the productivity, health and safety of the world's land and water, humic substances are increasingly in the scientific spotlight. However, their structures remain something of a mystery.

This book, with its molecular approach, brings the reader right up to date with current research, the key features being advanced analytical methods and physical measurements. Spectroscopic and mass-based approaches, in particular quantitative NMR, are discussed in detail as a means of attempting to understand the structures of these complex substances. Chromatographic techniques, including fluorescent fractionation, are also described. The use of coal-based humic substances for soil enhancement, water purification and soil remediation as an alternative to present methods is explored. Comprehensive, with contributions from international experts, "Humic Substances" will have a broad appeal to researchers in many disciplines, including agricultural and environmental science.
