mounted horizontally by adjustable, tripod style legs. The UV-C lamp apparatus was enclosed
with cardboard lined with aluminum foil to increase the containment of the UV light. The surface
on which the samples were placed on was covered with bench coat . The intensity of the UV-C light was measured using a
Newport power meter model 1928-C . UV-C light was turned
on at least 30 min to warm up before use.
