Use of Hexacyanoferrate (II) in Photobleaching of Rose Bengal

Abhishek Jain, Paridhi Kataria and Pinki B. Punjabi


The photobleaching of dye rose Bengal was carried in the presence of potassium hexacyanoferrate (II) and progress of the reaction was observed spectrophotometrically. The effects of various operating variables like pH, concentration of dyes and potassium hexacyanoferrate (II) and light intensity on the rate of the reaction was also observed. It was observed that photobleaching of dyes follows pseudo-first order kinetics. A tentative mechanism has also been proposed for the photobleaching of dyes in presence of potassium hexacyanoferrate (II).
