2. Decoloration could eliminate 94.36% of hematin from the hydrolysates and improved color of the final product.

3. And the mechanism and merits of decoloration coagulant used on treating dyestuff wastewater were reviewed.

4. Deproteinization, decoloration, desalination, and initial classification of glycosaminoglycan from Endothlium Comeum were investigated.

5. The decoloration effect of wastewater containing azo dye(reactive brilliant red X-3B) by white rot fungus was primarily discussed.

6. The oil decoloration rate of regenerated bleaching clay could reach 98.2 % in the optimum operation conditions.

7. The results showed that active charcoal particle has remarkable decoloration ability for the first xylose solution.

8. Either bleaching clay or clarifying clay possesses larger area,[sentencedict.com] higher absorbability and better decoloration as both are resulted from activation (or acidification) process of bentonite.
