氧化还原功能纤维的研究　Ⅷ．含正丙胺基吸附剂与Au^（3＋）的氧化还原反应机理

STUDY ON THE FUNCTIONAL REDOX FIBER Ⅷ.Redox Reaction Mechanism of the Absorbents Containing n-Propylamine Groups toward Au￣(3+)

通过元素分析、红外光谱分析、光电子能谱分析以及扫描电子显微镜分析等手段，证实含正丙胺基吸附剂与Ａｕ３＋的氧化还原反应过程中，氮原子邻近的羟基碳或Ｃ－Ｈ键被氧化，而氮原子并未参与氧化还原反应；吸附态Ａｕ（３＋）最终部分被还原成单质金；在非水介质中吸附在吸附剂上的金聚集成颗粒状。

By using EA,IR,ESCA and SEM,it is proved that carbon atom bonding to hydroxyl or hydrogen near nitrogen one is oxidized during the Au(3+)absorption of the absorbents containing n-propylamine groups,but nitrogen one is not,and part of Au(3+)absorbed is reduced into Au0;aggregates of gold absorbed on them in nonaqueous solvent are observed under SEM.
