Use of Safranine-O in Photocatalytic Reduction of Carbonate Ions

Photochemical reduction of sodium carbonate was investigated in presence of safranine-O. The progress of the reaction was observed spectrophotometrically at d_max=410 m. The effect of pH variation on the formation of formaldehyde and formic acid was investigated. Where two maxima were observed i.e. pH=6.0 and 10.0. Effect of various other parameter like concentration of carbonate intensity of light etc. The rate of photocatalytic reduction was also studied.
