中文摘要 | 隨著各種產業的蓬勃發展,許多複雜的有機物被合成與應用,染料即為其一,染整廢水的處理也成為相當重要的議題。而Fenotn法處理染整廢水具有經濟且快速之優點,因此本研究主要是探討以Fenton法處理甲基橙之可行性,以及Fenton試劑中的鐵離子濃度、過氧化氫濃度、硫酸濃度以及溫度等變因對反應之影響。由實驗結果得到以下結論:1.以Fenton試劑處理甲基橙具相當之可行性。2.甲基橙濃度在Fenton反應中的影響為在前段反應中為零級,但在末段反應卻變為一級。3.鐵離子濃度越大,反應越快;鐵離子濃度在Fenotn反應中為一級反應。4.過氧化氫濃度越大,反應越快,但趨近平衡。5.硫酸濃度越大,反應越慢。6.溫度愈高,去色反應愈快。7.處理濃度甲基橙為3.0×10^(-5)M的反應時,最佳處理條件為:[Fe^(3+)]=0.01M、[H_2O_2]=6.0×10^(-2)M、[H_2SO_4]=1.2×10^(-3)M、溫度=室溫8.速率反應方程式:(1)R=4.8[Fe^(3+)](2)R=24786[Fe^(3+)][Methyl Orange] |
英文摘要 | The Fenton has advantages such as fast reaction, low cost, and effective removal of chromaticity, over other wastewater treatment methods for the dyeing and finishing industry. Therefore, this research takes Methyl Orange as the primary subject to discuss the feasibility of the Fenton. It studies the effects of the variables in the Fenton reagent, such as the concentrations of ferric ion, hydrogen peroxide, sulfuric acid, and temperature, on the reactions. The conclusions obtained from the experiments are as follows: 1. It is feasible to use the Fenton reagent on Methyl Orange. 2. The effect of dye concentration to the Fenton reaction is zero order in the first stage and first order in the second section. 3. The effect of ferric ion concentration to the Fenton reaction is of the first order. The higher the ferric ion concentration, the faster the reaction, and the more effective the decoloration. 4. The higher the hydrogen peroxide concentration, the faster the reaction, and the more effective the decoloration. But, the rate will be fixed at a constant. 5. The higher the sulfuric acid concentration, the slower the reaction. 6. The higher the temperature, the more effective the decoloration. 7. The ferrous ion is more effective than the ferrous ion in decoloration process, and the higher the concentration, the faster the reaction. 8. The best conditions in processing 3.0×10^(-5)M Methyl Orange dye are: [Fe^(3+)]= 0.01 M, [H_2O_2]=6.0×10^(-2)M, [H_2SO_4]=1.2×10^(-3)M, Temperature=room temperature 9. The formula for Reaction Rate: (1)R=4.8[Fe^(3+)] (2)R=24786[Fe^(3+)][Methyl Orange] |
