用Fenton技术去除水中盐酸左氧氟沙星
Removal of Levofloxacin Hydrochloride in Water by Fenton Technique
摘要
Abstract
We studied the effect of Fenton advanced oxidation on the removal of levofloxacinhydrochloride in water,and investigated the effects of n (H2 O2 ):n (Fe2+ ),H2 O2 dosage,initial pHvalue,reaction time and initial mass concentration on the removal efficiency.The results show thatthe removal rates of levofloxacin hydrochloride,chemical oxygen demand (by K2 Cr2 O7 ,CODCr )andtotal organic carbon (TOC)increase first and then decrease with the increase ofn (H2 O2 ):n (Fe2+ )inthe range of 5—25.When the dosage of H2 O2 was 15 mL/L,the removal rates of levofloxacinhydrochloride,CODCr and TOC are 88.40%,59.52% and 33.80%,respectively.When pH=3,theremoval rates of levofloxacin hydrochloride,CODCr and TOC are 92.40%,59.52% and 34.51%,respectively.The removal rate of levofloxacin hydrochloride,CODCr and TOC gradually increase withthe time,and the removal rate decrease with the initial mass concentration.When the reaction time is 3 h,the removal process is basically completed.The effect of Fenton advanced oxidation on theremoval of levofloxacin hydrochloride in water is the best at the conditions of pH=3,temperature is20 ℃,H2 O2 dosage is 15 mL/L,n (H2 O2 ):n (Fe2+ )=10,the removal efficiency is 96.40%.关键词
