中文摘要 | 本篇論文利用聚胺醣(Chitosan)纖維織物吸附流動水溶液之Cu++與Zn++,進行熱力學與動力學之研究。首先在固定循環水流量下,以不同層數之織物對Cu++與Zn++吸附性實驗結果顯示:聚胺醣纖維織物之層數愈多,則水中金屬離子的消除速率愈大,但纖維對於金屬離子的吸附率減小。另以固定織物層數,改變循環水流量,針對Cu++與Zn++之吸附性實驗結果顯示:水洗流量存在一個臨界值,當流量未達到此值時,水中金屬離子的消除速率保持於一個定值,當流量超越臨界值以上,則水中金屬離子的消除速率顯著提高,此流量臨界值與金屬種類無關。 |
英文摘要 | The fabrics of chitosan was used to absorb the Cu + + and Zn + +ions from the solutions of CuSO4 and ZnSO4 in the flow form. The dynamic absorption was studied by using the thermodynamic and kinetic method. The absorption of Cu++ and Zn++ on chitosan fabrics was first investigated under the fixed flow rate. The experimental results reveal that the more the layers of chitosan fabrics is loaded, the more the elimination rate of ions is in water, but the less the absorption rate of metal ions is on chitosan fibers. The absorption behavior was then investigated for the fabrics of fixed layers under different flow rates. The experimental results show that there is a critical flow rate. The elimination rate of metal ions in flow maintains a constant as the flow rate is below the critical value, and the elimination rate increases obviously as the flow rate is above the critical value. However, the critical flow rate does not relate to the kinds of metal ions. |
