Abstract
The widely used fluoroquinolone (FQ) antibiotics have become emerging contaminants due to their unconstrained usage. A prompt, straightforward, précised, and advanced technique named fluorescence spectroscopy was applied to characterize and semi-quantify FQs. However, excitation wavelengths on the comparable ranges of FQs and ubiquitous humic substance (HS) complicate their identification in the mixture. This study develops a simple spectral technique that affirms the individual identification of FQs and HS in the natural environment. The following characteristics and methods can demonstrate the traces of FQs in the environment-
• Presence of fluorophore at Excitation/Emission = 225–230/285–295 nm wavelength in excitation-emission matrix (EEM) and parallel factor analysis (PARAFAC) models.
• FQs and HS have fluorophores at excitation wavelengths of 275 nm and 325 nm in PARAFAC analysis. Unlike HS, the notable spectral presence in <350 nm emission during 275 nm excitation in FQs ensures their distinct identification in the mixture.
• FQ affirming component intensity at Excitation/Emission = 225–230/285–295 nm and the intensity <350 nm emission during 275 nm excitation are considered in conjunction to quantify the amount of least FQ in any environmental sample.
