摘要

本研究调查了从橡树皮和洋葱皮等天然产品中提取的萃取物对涂饰过程中皮革中六价铬（铬 (VI) 或 Cr (VI)）形成的影响。为确保铬（VI）的形成，对成品皮革样品进行了不同条件下的老化处理，包括紫外线照射。根据 ISO/FDIS 17075 标准方法，使用 PC 紫外可见分光光度计在 540 纳米波长处测量每个皮革样品中的铬（VI）含量。结果表明，在所有老化条件下，柞树皮层和薤白提取物都能显著减少皮革中铬（VI）的形成。

Reduction of Cr (VI) Formation in Leather with Herbal Extracts

This study investigates the effects of extracts from natural products such as oak bark, and onion peel, on the formation of Hexavalent Chromium (chromium (VI)) or (Cr (VI)) in leather during the finishing process. To enable chromium (VI) formation, finished leather samples were aged under various conditions, including exposure to UV light. The amount of chromium (VI) in each leather sample was measured using a PC UV-Visible spectrophotometer at 540 nm based on the ISO/FDIS 17075 standard method. The results showed that extracts from Quercus cortex, and Allium cepa significantly reduced chromium (VI) formation in the leather under all aging conditions.
