Study the Effect of Titanium Oxide Nanoparticles on Rhodamine Dyes and Using it for Environmental Improvement

This research investigates the photocatalytic degradation of Rhodamine-B (Rh-B) dye using titanium dioxide (TiO 2 ) nanoparticles. A series of Rh-B solutions with varying concentrations were prepared, and the influence of TiO2 at different weight ratio (3, and 5)% was assessed under ultrasonic treatment. The mention of carbonyl groups might need more explanation, as Rhodamine-B (Rh-B) typically doesn't have strong carbonyl absorption. It may be better to state that the shift in absorbance indicates the degradation or structural changes in Rh-B due to photocatalysis. The results demonstrated that the photocatalytic activity of TiO2 nanoparticles effectively facilitated the degradation of Rh-B, with removal efficiencies improving with increased TiO2 concentration and exposure time to ultrasonic waves. The best result was get on it at the concentration (5%) of added TiO2 nanoparticles, were its represent the high Removal of dyes equal to (71.25%) at the time (20min). Key Word: Rh-B, TiO2, sonocatalysis.
