Photochemical Reaction Between Rose Bengal and Benzophenone

Bindu Kataria

Photochemical reaction between rose bengal and benzophenone was monitored spectrophotometrically in the presence of benzophenone. The effect of various parameters like pH, Concentration of dye, concentration of bnzophenone etc. has been observed. The photochemical reaction of dye follow pseudo –first order kinetics. A tentative mechanism for photochemical reaction between rose bengal and benzophenone has been proposed.
