中文摘要 | 以四種過渡金屬離子(Co���均ANi���均ACu���均AZn���均^和NaX及NaY沸石進行 不同交換度的交換反應,以滴定法及原子吸收光譜法確認交換度,從 1 %至 60 %。 以感 應耦合電漿原子放射光譜法及熱重分析法分析金屬交換沸石的組成。利用 X- 光繞射法及微 差熱分析法探討金屬交換沸石的熱穩定性。 |
英文摘要 | Four transition-metal ions (Co����, Ni����, Cu����, Zn����) were exchanged with sodium cations of NaX and NaY zeolites on different degree of exchange. The degree of exchange was confirmed by the titration method and atomic absorption spectrometry from 1% to 60%. The chemical composition of these ion-exchanged zeolites was analyzed by the inductively coupled plasma-atomic emission spectrometry and thermogravimetry. The thermal stability of the metal-exchanged zeolites was investigated using X-ray diffraction method and differential thermal method. |
