摘要
实验主要研究高锰酸钾氧化方法对水环境中普遍存在的红霉素的去除效率。研究了红霉素初始浓度、溶液p H、反应温度和高锰酸钾投量对高锰酸钾氧化去除红霉素效率的影响。结果表明,在不同水处理条件下,接触反应30 min后,红霉素的去除率均达到70%以上。研究表明,随红霉素初始浓度的增加,其去除率呈降低趋势;溶液p H对红霉素的去除率存在显著影响,当p H为5.5~8.0时,红霉素的去除率随溶液p H的增加而降低;随反应温度和高锰酸钾投加量的升高,红霉素去除率也随之升高。
This study focused on the removal of erythromycin widespread in water environments by potassium permanganate oxidation. The effects of initial concentrations of erythromycin, solution p H, reaction temperature and the dosage of potassium permanganate on the removal efficiency by potassium permanganate oxidation were examined. The results showed that under different water treatment conditions, a high removal rate of erythromycin（〉70%）could be achieved in 30 min of reaction time. As erythromycin initial concentration increased, the removal rates decreased. The effect of solution p H was significant on the removal efficiencies of erythromycin. Within the p H range of 5.5-8.0, removal efficiency of erythromycin decreased as the p H increased.As the reaction temperature and the dosage of potassium permanganate increased, removal efficiency of erythromycin was also increased.
