Methods

Summary

The actual quantitative efficacy of the Photocide process in terms of energy cost for various potential target contaminants is required in order to determine the competitive strength of this technology. The experiments to realize this quantificiation will be conducted using an existing variable wavelength light source that can be used to illuminate samples of various types using differing wavelengths, intensities and durations of illumination. Different target waste organic molecules with three selected non-toxic dyes will be used to determine the efficacy of the Photocide process. One of the dyes will be Methylene Blue, another will be a previously identified alternative wavelength absorber and a third food dye will be attempted. The quantity of target waste that is destroyed by the Photocide process will be assessed through a standard gravimetric concentration ladder as measured by visible light spectrum absorbance in a spectrophotometer. If funding is sufficient, various pHs and a broader range of target organic wastes will be destroyed using the Photocide process.
