Abstract
Examination of published methods for the determination of vegetable matter in burry wools containing a high percentage of burr indicates that only caustic-soda dissolution affords a reliable technique. This method is suitably modified and a new method, based on differential dye absorption, is developed. It is shown that the two methods give values of reasonable accuracy, provided that attention is paid to sampling and to prior calibration by the use of appropriate samples of the components.Keywords
