Somayyeh Dehghani, Ahmad Jonidi Jafari, Mahdi Farzadkia, Mitra Gholami
Presence of antibiotics in the environment may cause potential risk for aquatic environment and organisms. In this research, Fenton oxidation process was offered as an effective method for removal of antibiotic sulfamethoxazole from aqueous solutions. The experiments were performed on laboratory-scale study under complete mixing at 25±2°C. The effects of initial antibiotic concentration, molar rat...... hiện toàn bộ
