| 摘 要： | 将壳聚糖与膨润土混合制得一种吸附剂。将其用于染料溶液的脱色、陈醋的澄清、中药注射液中鞣酸的清除等，脱色率为97％，鞣酸脱除率为50％，陈醋的透光率为25．8％。通过X射线衍射图讨论了膨润土的改性机理。改性后膨润土的片状层结构未发生变化，壳聚糖仅仅吸附在膨润土的内外表面。

| Abstract: | A kind of absorbent is made from the combination of chitosan and bentonite. The absorbent is used for absorption of tannic acid in Chinese medicines, decolorization of used dyestuff solution, and clarification of old vinegar. The decolorization rate is 97%. The absorption rate of tannic acid is 50%. The transmittance of old vinegar is 25.8%. The structure change of bentonite and the mechanism of modification are discussed based on XRD results that the structure of bentonite does not changed and chitosan is absorbed on the surface of bentonite. |
