Abstract :
Optical pH measurement method based on the color change from the organic dye film was examined. Six pH indicators were selected for wide pH measurement range. Absorption spectra of the visible light were evaluated to six pH indicators. Moreover, pH valuation of the absorption spectra was evaluated for the optical pH measurement method application.
