Abstract:
This research investigates the efficiency of advanced oxidation processes for the removal of green
and red reactive dyes. These processes are photolysis (with only UV lamp), oxidation (with only potassium
persulfate) and photooxidation (with UV lamp plus potassium persulfate) processes. All processes were done
in a simple UV reactor. Firstly, the absorption spectra and linear calibration graphs of both reactive dyes were
carried out using UV-Visible spectrophotometer. After that the conditions of treatment processes were
examined such as flow rates, types of tubing for roll round the UV lamp, sample volumes, UV lamp powers,
potassium persulfate concentrations and dye concentrations. Under optimum conditions, a 1.13±0.06 mL/min
of flow rate, a PTFE tubing (200 cm length, 0.86 mm i.d.), a 10 mL of sample volume, a 36 W of UV power,
a 3.0 %w/v of potassium persulfate and a 350 mg/L of green and red dye were selected. From the results, the
photolysis process of green and red dyes achieved 100% dye removal in 80 mins, respectively. For the
oxidation process, a green dye was removed 35.95% of the dye in 90 min, while a red dye was removed
18.33% of the dye in 60 min. And for the photooxidation process, green and red dyes achieved 100% dye
removal in 25 mins, respectively. Results also revealed that the photooxidation process was higher efficiency
for green and red removals than the photolysis and oxidation processes, respectively
