Retrospective Theses and Dissertations

A comparison of the aluminum-chloride and sulfuric-acid methods for the quantitative estimation of wool in cellulosic admixtures has been made by determining their effects on the weight, ash, total sulfur, and sulfate sulfur of wool;Change in weight of wool by the aluminum-chloride method varied from -2.1 to +1.9 percent for 32 determinations which averaged -0.2 +/- 0.9 percent; for five sets of six parallel determinations the means ranged from -1.2 to +1.0 percent. Change in weight of wool by the sulfuric-acid method varied from -0.6 to +2.4 percent and averaged +0.9 ...
