Preparation of Chitosan Loaded Bentonite Absorbent
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.
