Degradation of ciprofloxacin by UV/H2O2 process
摘要
Abstract
The degradation of ciprofloxacin in UV/H2O2 process was investigated with a low-pressure UV lamp system.The influence of initial pH values,H2O2 concentration and water quality was discussed;the degradation products of ciprofloxacin were also analyzed.Results show that ciprofloxacin displays a pH-dependent degradation and the neutral condition is more favorable.Reaction rates increased with the increasing of H2O2 concentration,and the optimal H2O2/ciprofloxacin molar ratio at which the highest reaction rate constant is reached is 2 000.In UV direct photolysis,degradation rates of ciprofloxacin in natural water are higher than those in ultrapure water;while in UV/H2O2 process,the degradation rates in natural water are lower than those in ultrapure water.Moreover,several degradation products such as propanedioic acid,glycerin,1,4-benzenedicarboxylic acid,and some aliphatic acids etc.forming in the degradation of ciprofloxacin in UV/H2O2 process are identified by GC-MS.关键词
