摘要
本项目为国家自然科学基金资助项目。本文采用阳离子交换色谱、可见光谱和红外光谱等方法,分别对碱度为0％、33％及糖还原碱度为0％、 33％的四种硫酸铬鞣液的配合物组份、电荷、分子大小和含量进行了研究,并对这些组份可能的结构进行了推断,结果表明:四种硫酸铬鞣液的配合物组份、电荷、分子大小和含量都较均匀,但糖还原的硫酸铬鞣液比非糖还原的硫酸铬鞣液含有更多的组份、其电荷和分子大小分布更均匀。当鞣液碱度升高时,虽阳电荷组份逐渐增多,但各组份的百分含量分布仍较均匀。
The components, charges, molecular sizes and percent contents of comple-
xes in basicity 0%、33% and glucosereduced basicity 0%、33% chrome sulfate
tanning liquors were studied by cation-exchange chromatography、visible
and IR. absorption spectra etc. Some deductions were made on the possible
structurts of these components.The results showed that four kinds of chrome
sulfate tanning liquors all had an even distribution in the molecular sizes
charges and chrome contents with each component, but glucose-reduced chrome
sulfate tanning liquors were even better. When basicity was raised, cationic
components were gradually increasing, but the distribution of percent contents
with each component was still evenner.
