Investigation and Evaluation of Degradability of Ibuprofen from Wastewater by Using Fenton Process
2017
Pharmaceutical residues are considered as emerging environmental problem because of their potential toxicology risk on living organisms. Environmental problem of pharmaceuticals are persistence to the aquatic ecosystem even at low concentrations ( µ g/L-ng/L). Conventional wastewater treatment plants are not enough to remove an emerging solution. Ibuprofen (IBF), a non-steroidal anti-inflammatory drug (NSAID), is a most widely used medicine in almost part of world. In present study, under laboratory conditions, coagulation followed by advance oxidation, using H 2 O 2 and FeSO 4 (Fenton process) is used to degrade the concentrations of ibuprofen from water were conducted. Fenton process is known to be most effective and common methods for the treatment of such wastewaters. In the present study H 2 O 2 was used with FeSO 4 for the treatment ibuprofen and effects of H 2 O 2 , FeSO 4 concentrations COD and TOC removals. Experiments with optimal concentrations of H 2 O 2 and FeSO 4 were carried out by chancing pH, temperature, stirring and residence time of solution (2-6), room temperature, (10,20,30 min) and (30,60,90 min) respectively. Concentration of FeSO 4 and H 2 O 2 were selected as (30,75,150 mg/L). After processing, 150 ml of samples taken out from the upper layers of sample COD and TOC tests were conducted.
