Summary, etc. <p class="Abstract" style="text-align: justify;"><span lang="EN-GB">The photocatalytic degradation of </span><span lang="EN-GB">ciprofloxacin<span> (CFX) has been investigated using Aeroxide<sup>®</sup> P-25 TiO<sub>2</sub> photocatalyst in the presence of solar as well as artificial radiation</span>. The effects of different operating parameters like initial concentration of CFX, catalyst loading, <em>p</em>H of solution and effect of co-existing ions on photocatalytic degradation of CFX have been investigated with a view to establish the optimum operating conditions. It is observed that as the initial concentration of CFX increases, the rate of photocatalytic degradation decreases. Optimum catalyst loading is observed at 1 g L<sup>-1</sup> for CFX concentration of 100 mg L<sup>-1</sup>. Over the <em>p</em>H range 3-11, maximum degradation rate occurs at <em>p</em>H 9. The mechanism and intermediates formed during the photocatalytic degradation of CFX are discussed based on UPLC-MS/MS analysis. From kinetic studies, it is found that the photocatalytic degradation obeys pseudo-first order kinetics. The degradation rate constant using solar radiation is about 1.7 times higher than that under artificial radiation.</span></p><br />
