A strong adsorbent TEA-GO for Cu(2+) is prepared using TEA modified GO nanosheets. FT-IR and XPS results show that epoxy groups on GO are eliminated, and simultaneously hydroxyl groups and C-N dominate the surface groups of TEA-GO. The increased equilibrium capacity of TEA-GO for a high initial concentration of Cu(2+) makes it a promising adsorbent for heavy metal ions.
采用TEA修饰的氧化石墨烯纳米片制备了一种用于吸附Cu(2+)的强吸附剂TEA-GO。傅里叶变换红外光谱（FT-IR）和X射线光电子能谱（XPS）结果表明，氧化石墨烯上的环氧基团被消除，同时羟基和C-N主导了TEA-GO的表面基团。TEA-GO对高初始浓度Cu(2+)的平衡吸附容量增加，使其成为一种有前景的重金属离子吸附剂。
