Degradation of Phenol Using Sonolysis and Photolysis by TiO2/RHAC Catalyst and Analysis with Spectrophotometer UV-VIS and HPLC

This study focuses on the degradation of phenol in aqueous solutions using photolysis and sonolysis methods. It investigates impact catalyst mass, types light (UV-A, UV-C, visible light), (RHAC, TiO2, TiO2/RHAC), processing time degradation. The are analyzed before after Spectrophotometer UV-Vis HPLC. research aims to understand factors influencing provide a basis for further studies enhance efficiency removal. Results show significant improvements percentages by TiO2/RHAC as catalyst. Sonolysis achieves 20.82% with catalyst, which increases 50.57% Photolysis 29.06%, rises 91.99% highest percentage is achieved UV-A 5 hours mass 30 mg HPLC analysis confirms decreased concentration presence intermediate compounds. demonstrates promising potential efficient solutions.
