摘要
对鞣花酸防治皮革中Cr(Ⅵ)的应用条件进行了研究。结果表明:将鞣花酸应用于皮革加脂过程中,能有效降低皮革中Cr(Ⅵ)的含量;在加热、紫外光照三天的过程中,皮革中Cr(Ⅵ)含量均小于3 mg/kg,符合欧盟要求。
The application of ellagic acid to leather for preventing chromium(Ⅲ) from chromium(Ⅵ) has been studied.The result showed that ellagic-acid has the ability to reduce the content of chromium(Ⅵ) in the leather when it was used in the process of fatliquoring.The content of chromium(Ⅵ) in the leather is less than 3 mg/kg and meets the standard of the EU requirements even after heating and enlightening under ultraviolet light,for 3 days.
