Comparative studies of Rhodamine B decolorization in the combined process Na2S2O8/visible light/ultrasound
P Zawadzki - Desalination and water treatment, 2021 - Elsevier
In this study, the possibility of rhodamine B (RhB) decomposition in the presence of
ultrasound (US) and sodium persulfate (Na 2 S 2 O 8) activated by visible light (Vis) was
investigated. A combination of these processes (Na 2 S 2 O 8/Vis/US) were examined. As a
part of this study, the optimal dose of Na 2 S 2 O 8, glucose dose, reaction time, and RhB
concentration were selected. In addition, radical scavenger test was conducted. Under
optimal conditions (RhB concentration= 10.0 mg dm–3; pH= 6.0; reaction time: 60.0 min; Na …
