用氧-18稀释法测定了水在0~40μ汞蒸汽压下在再生纤维素上的吸附。结果表明，在70℃下抽真空可使纤维素干燥至含水率小于0.04%，并与Taylor对粘胶纤维的吸附等温线进行了比较，还表明-18氧在纤维素和水之间没有交换。
The adsorption on regenerated cellulose of water at vapor pressures of 0 to 40 μ Hg has been measured by an oxygen-18 dilution technique. The results showed that cellulose may be dried to less than 0.04% moisture by evacuation at 70 °C. The adsorption isotherm was compared with that of Taylor for viscose rayon.It was also shown that oxygen-18 does not exchange between cellulose and water.
