Effect of Oxidation Agents on Photo-Decolorization of Vitamin B<sub>12</sub> in the Presence of ZnO/UV-A System

Effect of Oxidation Agents on Photo-Decolorization of Vitamin B<sub>12</sub> in the Presence of ZnO/UV-A System

The aim of this work was to apply the many various oxidation agents namely H2O2, K2S2O8 and Fe2+ on the aqueous solution of vitamin B12 with the presence of ZnO. The results indicated that the use of the mixture of H2O2 and K2S2O8 in suspension of vitamin B12 and ZnO gave a maximum efficiency percen...
