摘要

本研究使用RB19染料廢水，以Fenton程序進行染料去除反應，在不同鐵鹽作用下，加入硫酸根陰離子比較其去除效果，實驗以250 ml錐形瓶，在恆溫振盪器為之，溫度維持在30℃，轉速設定在160rpm，過氧化氫、鐵鹽、硫酸及氧化時間為操作變數。實驗結果顯示，Fenton氧化程序去除染料效果良好，且在相同加藥量下，硫酸亞鐵去除染料效果優於硫酸亞鐵銨；比較硫酸的影響，對於硫酸亞鐵銨負影響大於硫酸亞鐵。

The water sample synthetic RB19 was investigated for the removal of dye as function of ferric-salt and sulfuric acid during Fenton degradation in this study. The experiments were conducted in 250-ml flasks, which were capped and shaken in a isothermal oscillator tank with oscillation speed set at 160 rpm. The dosages of H2O2, ferric-salt, sulfuric acid and oxidation time are the operate parameters. These results show degradation in the Fenton process are feasible. The efficiency was in the order FeSO4•7H2O＞FeSO4(NH4)2SO4•6H2O. The FeSO4(NH4)2SO4•6H2O has larger negative effect for sulfuric acid dosage.
