Abstract

The open circuit potential of titanium in water may significantly vary under illumination. It has been suggested that this shift might have some relation to light effects on oxide film. Experiments were hence, designed to study the effect of illumination on corrosion potential of titanium and platinum in the pond water. The results indicated that the photoelectrochemical and organic photochemical reaction influence on the excursion of potential during day and night hours. Besides, the negative photo-potential were observed for titanium and platinum, indicating the presence of n-type semiconducting film even in presence of biofilm covering the respective surfaces. In addition, the dissolved nutrients within the biofilm were also estimated. It is concluded that “Mixed inhibitor” may strengthen the n-type semiconducting oxide film on these metal surfaces during the processes of ennoblement. The results based on these factors are discussed in detail
