【摘要】 采用BSTFA衍生化并结合GC-MS的方法鉴定出了硅藻引发17α-乙炔基雌二醇(EE2)光降解的中间产物10ε-17α-二羟基-1,4-乙炔基雌二烯-3-酮。对EE2的降解机理进行了探讨,认为EE2在光降解过程中,分子中的C3和C10原子容易受到电子的攻击,氧化生成羰基或羟基化合物。更多还原

【Abstract】 BSTFA derivatization coupled with GC-MS were used to identify photocatalysis degradation product of 17α-ethynylestradiol induced by Nitzschia hantzschiana.10ε-17α-Dihydroxy-1,4-ethinylstradien-3-one was identified.It could be concluded that in the course of photodegradation of EE₂,C3 or C10 atoms should be the sites at which is subject to the electron attack and oxidization of EE₂ into carbonyl or hydroxyl compounds.更多还原
