摘要
用γ -氨丙基三乙氧基硅烷与轻质二氧化硅反应 ,制得γ -氨丙硅氧烷离子交换树脂 ,由于其功能基位于固体表面 ,具有较快的吸附速度 ,在实验条件下 ,对Ag+ 的吸附在 15min内达到平衡 ,吸附后样品可用HNO3 洗脱 ,洗脱后样品具有较好的再生重复性能。
A new adsorption resin named poly-γ-aminopropyl siloxane was prepared by the reaction of aminopropyl triethyoxylsilicane with light silicon oxide.The resin had fast adsorption speed as well as good adsorptive capacity due to its surface functional group.It could be reused and had good repetitive quality after being rinsed by nitric acid.
