Clean-up of Contaminated Indoor Air Using Photocatalytic Technology
Abstract
A number of Sick Building Syndrome
studies have concluded that microorganisms,
endotoxins and VOCs in indoor air are involved in
the development and/or aggravation of allergies and
illnesses in buildings. The phototcatalytic indoor air
disinfection and detoxification technology provides
one of the most viable solutions to the growing need
to remediate and purify contaminated indoor air.
The experiments were conducted in a stainless steel
environmental chamber to quantitatively measure the
photocatalytic VOC destruction using Acetone as a
representative VOC. While monitoring the VOC
destruction, carbon dioxide (C02) levels were also
measured. By performing a mass balance between
the VOC destruction and C02 production, the
photocatalytic technology was found to be
completely effective. Dark control experiments were
performed for each condition to confirm the validity
of each experiment. The photocatalytic technology
tested in these experiments was demonstrated to
completely oxidize acetone at normal indoor air
atmospheric conditions.
