Titanium dioxide doped hydroxyapatite incorporated photocatalytic membranes for the degradation of chloramphenicol antibiotic in water

Abstract

BACKGROUND 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. RESULTS The degradation of chloramphenicol was measured by liquid chromatography‐mass spectrometry (LC–MS). The photocatalytic degradation experiments revealed that the highest degradation of 61.59% was observed for the PSf/4 wt% TiO2‐HAP nanocomposite membrane. CONCLUSION This study highlights the advantages of applying the photocatalytic TiO2‐HAP incorporated PSf composite membranes for pharmaceutical wastewater treatment applications. © 2020 Society of Chemical Industry

Hydroxyapatite/TiO2 Nanomaterial with Defined Microstructural and Good Antimicrobial Properties

“…The carbonate that occurred in samples probably came from the atmosphere. Further, the OH absorption bends at 1650 cm −1 (δ(OH)) and low-intensity broad bend at 3520 cm −1 (O-H stretching vibrations) suggested that no dehydroxylation had occurred during the formation of the HAp-TiO 2 nanocomposites [26,29]. The dehydroxylation of HAp took place before the decomposition.…”

“…37 In addition, the improper disposal of CAP-contaminated wastewater has been identified in water and even drinking water, which certainly causes major health issues in humans and animals. 38 Because of the increasing antibiotic drug pollutants in the global system, many researchers have been very enthusiastic about controlling or monitoring CAP using various analytical methods. In recent years, the conventional analytical techniques for the detection of CAP are high-performance liquid chromatography (HPLC), 39 LCmass spectrometry (LC-MS), 40 gas chromatography (GC), 41 gas chromatography-mass spectrometry, 42 Raman scattering, 43 chemiluminescence, 44 enzyme-linked immunosorbent assay (ELISA), 45 and antibody-based techniques 46,47 are frequently explored for CAP detection.…”

“…Therefore, China, Canada, and the United States monitoring the food safety and control department have set the minimum required performance limit of CAP as 0.3 μg kg –1 . In addition, the improper disposal of CAP-contaminated wastewater has been identified in water and even drinking water, which certainly causes major health issues in humans and animals . Because of the increasing antibiotic drug pollutants in the global system, many researchers have been very enthusiastic about controlling or monitoring CAP using various analytical methods.…”
