摘要：
The authors measured carbohydrates in rayons and a dissolving pulp using acid hydrolysis, anion exchange chromatographic separation of the resulting monosaccharides, and pulsed amperometric detection of the separated monosaccharides Analysis of the hydrolyzates without acid neutralization or monosaccharide derivatization proved effective in separating and analyzing low concentrations of D-xylose and D-mannose in the presence of D-glucose This allowed close approximations of hemicellulose in cellulosic products The rayons contained less than 4.0% hemicellulose and the dissolving pulp less than 3.5% hemicellulose.
