Photo-Degradation of Some Dyes using Ag-Loaded Titaniumdioxide


The photocatalytic degradation of organic dyes using TiO2 andsilver-loaded TiO2 has beenstudied. The dyes which were chosen (methyl violet, a cationicdye; Cibacron Blue FMR, areactive dye; and Maxilon Red GRL, a mono azo basic dye)represent the major structuralfamilies of organic dyes. Ag-loading dramatically reduceddegradation time. While theundoped TiO2 degraded about 63% of the total amount ofmethyl violet within 4 min,degradation rose to 95% with Ag-loaded TiO2 within the sametime period. The photo-decomposition of dyes was monitored as a function of pH anddissolved organic and inorganic matters.
