Three sets of disinfection experiments were being conducted; 1) UVC only, 2) Hydrogen peroxide only, 3) and UVC enhanced by filtered hydrogen peroxide.
Each set of experiment required all the lab skills I learned throughout the summer such as agar plating and using photoreactor.
The data turned out to be rather straightforward as both UVC only and H2O2 enhanced UVC killed over 99.99% of E. Coli within 1 minute of the experiment, and it turned out that inactivation by hydrogen peroxide only is rather negligible.
So, the 6 sets of 4watt UVC lamps that I used was way too strong to compare the effect of OH radical enhancement.
Although supposedly, I should have reduced the watt of the UVC lamp by half or so and conducted another set of experiment, unfortunately, time ran out, and I could not really do that part.
Anyways, still, I showed that the UVC lamps are super strong and effective in killing the E. Coli bacteria and I hope that the Korean Condo company would be satisfied regardless that their lamp will successfully disinfect the surface of their condos.
I had decent amount of fun doing lab at yale this summer and i hope rest of you guys would finish up your lab stuffs stronk.
