In the recent years, photocatalytic membrane process has gained interest in wastewater treatment applications. In this study, the ability of advanced oxidation technology coupled membrane process was evaluated during chloramphenicol (CAP) filtration. Titanium dioxide doped hydroxyapatite (TiO₂‐HAP) based photocatalytic membrane for chloramphenicol (CAP) degradation was investigated. The TiO₂‐HAP photocatalyst was synthesized by a facile hydrothermal technique and characterized by the transmission electron microscope, X‐ray diffraction, and FTIR spectroscopy. Varying concentrations of TiO₂‐HAP photocatalyst incorporated polysulfone (PSf) membranes were fabricated to enhance the photocatalytic activity and antifouling propensity. The photocatalytic activity of TiO₂‐HAP incorporated PSf membranes was evaluated by a low‐pressure cross‐flow lab‐scale photocatalytic membrane reactor (PMR) for degradation of chloramphenicol in water. These results were compared with pristine PSf membrane.

掺有二氧化钛的羟基磷灰石结合光催化膜降解水中的氯霉素抗生素

近年来，光催化膜工艺在废水处理应用中引起了人们的兴趣。在这项研究中，在氯霉素（CAP）过滤过程中评估了先进的氧化技术偶联膜工艺的能力。研究了二氧化钛掺杂的羟基磷灰石（TiO ₂ -HAP）基光催化膜对氯霉素（CAP）的降解。TiO ₂ ‐HAP光催化剂是通过简便的水热技术合成的，并通过透射电子显微镜，X射线衍射和FTIR光谱进行了表征。各种浓度的TiO ₂‐结合了HAP光催化剂的聚砜（PSf）膜可增强光催化活性和防污性能。通过低压横流实验室规模的光催化膜反应器（PMR）评估了掺入TiO ₂ -HAP的PSf膜的光催化活性，以降解水中的氯霉素。将这些结果与原始PSf膜进行比较。
