The effects of different methods of preparing cellulose nitrate on the determination of the D/H ratios of non-exchangeable hydrogen of cellulose

摘要: Abstract Cellulose nitrate prepared by different methods was subjected to elemental, isotopic, and spectroscopic analysis. nitration of wood powder contaminated, most likely nitrated lignin. cellulose did not contain this component, thus provides a more accurate measure the D/H ratios non-exchangeable hydrogen cellulose. However, directly from contained trace amounts hemicellulose nitrates completely nitrated. These conditions will cause significant errors in measured for samples. Analysis aliquots same samples two suggests that published δD values may be error 6–8‰ many cases occasionally as much 15‰.
