Figure 2c shows that the NO is generated from the photolysis
of HONO in the solar radiation zone and diffused to the ambient air.
All AOPs used in this study appeared to be capable of completely decolorizing the azo dye Remazol Black B within feasible reaction time, ranging from few minutes to 30 minutes, except UV alone as the dye seemed to be resistant to direct photolysis
. Fenton's process was found to be a suitable and promising treatment method as compared to other AOPs.
When flash photolysis
was applied instead of 20 Hz stimulation, the Ca sensitivity of release was decreased by a factor of 2, indicating that the intrinsic Ca sensitivity of fast releasing vesicles is heterogeneous (the remaining vesicles after 20 Hz stimulation are slower by a factor of 2).
The contribution due to photolysis
is negligible; for this reason, the LVREA due to the reactive species was not added in the photolysis

As already mentioned, photolysis
(film degradation due to light exposure in an inert atmosphere) of P3HT occurs at a rate which is several orders of magnitude slower than photooxidation .
Degradation processes under direct photolysis
did not contribute to the process of photocatalytic degradation; in the non-preheated condition percentages of degradation of 11% and 9.5% for the isothermal condition at 312 K were obtained.

and dark adsorption experiments were performed, results were depicted as well (Figure 9).
The COD reduction of the vinasse samples after photolysis
(without catalyst) is included for comparison.
The use of certain sunscreens, which can protect skin from ravages of sunlight, can also deposit peroxy and hydroxy radicals along with their photolysis
fragments on skin.
