The solution to overcome environmental pollution due to ciprofloxacin is degradation by using TiO2 nanoparticles. TiO2 nanoparticles performance is influenced by environment such as light source, pH solvent, duration of lighting and TiO2 nanoparticles mass. The residual levels determination of ciprofloxacin was carried out by using a UV-Vis spectrophotometer. Toxicity test of ciprofloxacin degradation products with TiO2 nanoparticles used Escherichia coli bacteria. Liquid Chromatography Mass Spectrometry (LCMS) was used to determine the type of ciprofloxacin degradation product with TiO2 nanoparticles. The optimum condition for the ciprofloxacin degradation with TiO2 nanoparticles is lighting for 5 hours by using a white mercury UV lamp and 50 mg TiO2 nanoparticles with pH solvent of 5.5. The toxicity of ciprofloxacin degradation product with TiO2 nanoparticles was low. The smallest degradation product identified with m/z was p-fluoraniline (m/z 111).

纳米二氧化钛降解环丙沙星的条件、毒性及降解途径的优化
环丙沙星的普遍使用往往是不合理的,因此造成耐药性等环境污染。克服环丙沙星对环境污染的解决方案是利用TiO2纳米颗粒降解环丙沙星。TiO2纳米粒子的性能受光源、pH溶剂、光照时间和TiO2纳米粒子质量等环境的影响。采用紫外-可见分光光度计对环丙沙星的残留量进行测定。二氧化钛纳米颗粒对环丙沙星降解产物的毒性试验。采用液相色谱-质谱法测定TiO2纳米颗粒降解环丙沙星产物的类型。TiO2纳米颗粒降解环丙沙星的最佳条件为:在白汞紫外灯下,溶液pH为5.5,溶液中TiO2纳米颗粒的浓度为50 mg,光照时间为5小时。TiO2纳米颗粒降解环丙沙星的产物毒性较低。用m/z鉴定出的最小降解产物是对氟苯胺(m/z 111)。版权所有©2021作者,BCREC集团出版。这是一篇基于CC BY-SA许可(https://creativecommons.org/licenses/by-sa/4.0)的开放获取文章。
