of Equally Potent Fluoroquinolone Antibiotics 

Journal/Source: Environ. Sci. Technol., 50 (17), 9533-9542, (2016); DOI: 10.1021/acs.est.6b01794


Data: diagram, table

Energy/Wavelength range: 253.7 nm

Resolution: 

Temperature: 298 K

Temperature dependence: no

Pressure/Concentration: 

Phase: aqueous solution (0.1 % HCl)

pH: 2 - 12 (pH was controlled using 10 mM phosphate buffer)


Comments: The apparent molar absorptivity and fluence-based pseudo-first-order rate constants for transformation of the six 
fluoroquinolones by direct photolysis at 253.7 nm were determined for the pH 2-12 range.
The apparent molar absorptivity was modeled as a function of pH by assigning each protonated/deprotonated species a specific molar 
absorptivity.
