Spectrochemical Elemental Analyses of Textiles and Textile Fibers
Among the numerous spectroscopic techniques and procedures available for analytical purposes, some ten are methods for the qualitative identification and for the quantitative estimation of the chemical elements, both metallic and nonmetallic. These ten different spectroscopic approaches are described very briefly. Three spectroscopic procedures have been of most importance in elemental analyses of textiles and textile fibers. These three, electronic (ultraviolet or visible) emission (or so-called spectrochemical analysis), x-ray fluorescence, and atomic absorption are described in detail. Applications of these three techniques are illustrated, mainly in the analysis of cotton cellulose fibers, as these are the more familiar analysis in the author’s laboratory and the chemical modification of cotton cellulose has created a special need for elemental analyses for a fairly wide number of both metals and nonmetals. However, the techniques described are applicable with little if any modification to similar analyses of any natural or synthetic fiber. They can also be applied without modification to the analysis of yarn or fabric. The three techniques are compared with reference to such factors as, speed of analysis, sensitivity, cost of original equipment, requirements for operator skill, etc.
