Abstract
Hematoxylin is a naturally occurring chemical used as the basis of a dyestuff.The collagen hydroslate is the main composition which constitutes leather.In order to use the hematoxylin dye leather we use the collagen hydroslate as simulacrum,collagen hydroslate reacting with metals ion was invesgated by the UV and fluorescence spectroscopy.Results show in different pH the same metal ion have different react ability with hematoxylin.The hematoxylin have small change in acidity rang,great change in alkalescence rang.Different metals ion whisker with hematoxylin is different.
