Özet
The effect of walnut shell extract ( Juglans regia) on chromium (VI) formation in leather during the finishing process is investigated in this study. The walnut shell extract composition was determined using gas chromatography. To enable chromium (VI) formation, finished leather samples were aged under various conditions, including exposure to ultraviolet light. The amount of chromium (VI) in each leather sample was measured using a Shimadzu UV-1601 PC UV-visible spectrophotometer at 540 nm based on the ISO/FDIS 17075 standard method. The results showed that the extracts from walnut shell ( Juglans regia) significantly reduced chromium (VI) formation in the leather under all aging conditions.
