【摘要】 用透析袋和玻璃纸为透析材料，分别透析去除丝素溶液中Ｃａ２＋，并就透析后丝素溶液中的Ｃａ２＋含量和含氮量进行了分析对比．试验结果表明，用透析袋和玻璃纸透析９８ｈ后，Ｃａ２＋的含量均从２０．７８％降至０．０４％，含氮量分别从１．５２％降为０．６２％和０．５４％．实验证明玻璃纸可以代替透析袋透析脱除丝素溶液中的Ｃａ２＋．更多还原

【Abstract】 The cellophane and visking dialysis tubing were used in the experiment for dialyzing the Ca2+ from fibroin solution. This experiment compared the content of Ca2+ and N in the fibroin solution after which weredialyzed by the cellophane and visking dialysis tubing. The experiment results showed that the Ca2+ contentall were decreased from 20. 78% to 0. 04%, and the N content was cut down from 1. 52% to 0. 62% and0. 54% after the fibroin solution was dialyzed by visking dialysis tubing and cellophane separately. The experiment proved that the visking dialysis tubing can completely be replaced by cellophane for this use.更多还原
