【摘要】 以250W照明金属卤化物灯为光源研究了水中17β雌二醇(E2)在类Fenton体系中的光降解。结果表明,Fe(Ⅲ)/H2O2体系能有效地光降解E2。pH3～6范围内,E2光降解率及反应初始速率随酸度的增大而增大;H2O2初始浓度越大,E2降解率及反应初始速率越大;E2初始浓度越低,E2降解率越高,反应初始速率越低。更多还原

【Abstract】 Photodegradation of 17β-estradiol （E2） in water induced by a Fenton-like system was investigated under a 250 W metal halide lamp （λ≥313 nm）. The results indicated that E2 could be photo-decomposed efficiently in Fe（Ⅲ）/H₂O₂ system. Over the range of pH 3.0⁶.0, the higher acidity of the solution, the higher the degradation efficiency and initial rate of E2 were. The degradation efficiency and initial rate of E2 increased with increasing of initial concentration of H₂O₂ . The lower the initial concentration of E2, the higher the degradation efficiency of E2 was and the lower the initial rate of E2 was.更多还原
