Photo-oxidative Decolorization of Brilliant Blue with AgNPs as an Activator in the Presence of KSO and NaBH.

The decolorization of brilliant blue (E133) in aqueous solution by KSO and NaBH with AgNPs as an activator was studied spectrophotometrically under normal laboratory conditions. Batch experiments were performed to investigate the effects of reaction time, initial dye concentration, activator concentration, solution pH, and temperature on the decolorization of E133. KSO and NaBH did not decolorize the dye E133 in the absence of AgNPs.
