Dye indicator for the effectiveness ot titanium dioxide water purification. - 125 p.

Adviser: John Duffy.

Thesis (M.S.Eng.)--University of Massachusetts Lowell, 2007.

The potential of an oxidation sensitive dye as a clear and real time indicator of the effectiveness of a titanium dioxide solar water purification system was explored with Indigo carmine selected as the best candidate. A pill created with food grade Methocel(TM) (hypromellose) as a binder was used for transport and rate of release.Subjects--Topical Terms:

520 $a The potential of an oxidation sensitive dye as a clear and real time indicator of the effectiveness of a titanium dioxide solar water purification system was explored with Indigo carmine selected as the best candidate. A pill created with food grade Methocel(TM) (hypromellose) as a binder was used for transport and rate of release.
520 $a Experiments were performed to determine the correlation between dye color change and bacterial destruction. The dye was found to be a conservative measure of bacterial destruction as full color change from blue to clear occurred well after the bacteria was destroyed in normal tests. Further there are no anticipated health effects due to the ingestion of these pills as the materials are FDA approved food additives. Additionally the binder does not support bacteria growth and does not degrade the TiO2 film on the bottle. The pill cost of less than one cent makes it economical.
