However, in the environment, scopolamine may cause pollution to water and soil. Therefore, it is of great scientific significance and practical value to study its degradation mechanism.This study used photocatalytic methods to investigate the degradation mechanism of scopolamine and explored the effects of factors such as light exposure time, light intensity, pH, and oxygen content on its degradation. The experimental results show that under ultraviolet light, scopolamine is degraded by a free radical mechanism, in which hydroxyl radicals (•OH) are the main products. Increasing the light exposure time and intensity can promote the reaction rate, while acidic environments and high oxygen content have little effect on the reaction rate.精品文档---下载后可任意编辑This study provides a new idea for the degradation of scopolamine in the environment and provides a reference for its efficient degradation and environmental protection.Keywords: scopolamine, photocatalytic degradation, free radical mechanism, hydroxyl radicals, influencing factors.
