A novel amine modified double-walled silica nanotube for adsorption of Cu2+ in aqueous solution |
| 초록 |
Double-walled silica nanotube (DWSNT) was utilized as a potential material such as catalysis, adsorbent and sensor. In this study, DWSNT which is surface modified by amine (primary(1°), secondary(2°), tertiary(3°) amines) was applied to adsorb Cu2+ in aqueous solution. The mechanism of Cu(OH)2 crystals growth was imply that the reaction between complex Cu2+ and OH- dissociated from water on the surface of amine functionalized DWSNT. The adsorbed Cu2+ was analyzed by inductively coupled plasma (ICP) and the capacity of adsorption shows following order: 1° amine ＞ 2° amine ＞ 3° amine. The growth of Cu(OH)2 crystals was investigated by X-ray diffraction (XRD) for determination of the mechanism. Also, Field emission gun scanning electron microscopy (FEG-SEM) and high-resolution transmission electron microscopy (HR-TEM) are used to show the internal-external structures of DWSNT. The modified DWSNT by crystallization technique shows a potential application in various fields. |
