Abstract
For determination of holocellulose, the residual yield and its chemical composition during delignification by acidified sodium chlorite have been studied for bamboo (Phyllostachys heterocycla) and Sargassum (Sargassum horneri). It was then found that along with the extended number of chlorination, the residue became yellowish, and then whitish. Accordingly, the holocellulose yield was reduced. Thus, in order not to lose any part of the holocellulose, the number of chlorination was found to be minimized so as for the residue to remain yellowish. Subsequently, lignin and ash corrections were made on the yellowish residue to determine the accurate holocellulose content. Such a modified procedure for the holocellulose determination was proposed in this study.
