Analytical Methods in Wood Chemistry, Pulping, and Papermaking

In its broadest sense, and according to the traditional conception, wood chemistry is a comprehensive discipline, ranging from fundamental studies to practical applications. The manifold constituents, located in different morphological regions in the wood, results in an extreme complexity of wood chemistry. Ever more sophisticated endeavors needing fundamental studies and advanced analytical methods are necessary in order to delve deeper into various problems in pulping and papermaking. Gradually, new, improved ana lytical methods, originally developed for research purposes, are currently replacing many of the old "routine" methods in practical applications. Because of the expanse of the subject, an attempt to write a book of this size about analytical methods seems, perhaps, too ambitious. Of course, a whole book series of several volumes would be necessary to cover this topic completely. However, there is undoubtedly a need for a more condensed presentation which does not go into experimental details, but is limited to the basic principles of the analytical methods and illustrates their applica tions. The emphasis is on more advanced and potential methods, and partic ularly on those based on different types of spectroscopy and chromatography.

This is a concise and critical treatise on the most important analytical methods in wood chemistry related to pulping and papermaking. The emphasis is on principles and important applications, needed not only in academic research, but especially for industrial applications. It starts with basic information on the chemical composition with analytical techniques of wood and wood components of the main groups (carbohydrates, lignin, and extractives), proceeds to the methods used for the characterization of the chemical properties of wood and pulp fibers (with special emphasis on the fiber surfaces), and concludes with the methods applied to the analysis of pulping and bleach liquors, papermaking waters and effluents, and those used for the analysis of inorganic components in wood and pulps.
