Enhanced efficiency of treatment of TNT wastewater by internal electrolysis reaction use bimetalic materials Fe-Cu

In this article, wastewater containing 2,4,6 trinitrotoluen (TNT) was treated by internal microelectrolysis with bimetal Fe-Cu materials. Components of TNT pollutant content was identified by HPLC method. Examined factors: pH, time, temperature, concentration of Fe-Cu bimetal to efficient treatment of TNT in the wastewater. With conditions at pH 5, bimetal Fe-Cu dosage of 50 g for l litre of wastewater, TNT original content in the wastewater infected about 95-106.4 mg/l, temperature of 25 0 C, after 6 hours of processing time, content TNT rest 0.2 - 0.5 mg/l, after 6 hours not observed. | Journal of Science and Technology 54 (4B) (2016) 11-18 ENHANCED EFFICIENCY OF TREATMENT OF TNT WASTEWATER BY INTERNAL ELECTROLYSIS REACTION USE BIMETALIC MATERIALS Fe-Cu Vu Duy Nhan1, 2, *, Nguyen Van Tu1, Nguyen Thi Nhan1, Le Mai Huong3, Le Thi Mai Huong4, Cao Dinh Thanh5 1 2 Institute of Chemistry and Materials, 17 Hoang Sam Street, Cau Giay, Hanoi Graduate University of Science and Technology, VAST, 18 Hoang Quoc Viet, Hanoi 3 4 Institute of Natural Products Chemistry, VAST, 18 Hoang Quoc Viet, Hanoi Isntitute for technology of radioactive and rare elements, VINATOM, 48 Lang Ha, Hanoi 5 Vietnam Atomic Energy Isntitute, VINATOM, 59 Ly Thuong Kiet, Hoan Kiem, Hanoi * Email: vuduynhantshu@gmail.com Received: 15 August 2016; Accepted for publication: 10 November 2016 ABSTRACT In this article, wastewater containing 2,4,6 trinitrotoluen (TNT) was treated by internal microelectrolysis with bimetal Fe-Cu materials.

In fact, about 50 years after World War II, in the building where Army ammunition factory still find large amounts of TNT and their isomers [3, 6]. This demonstrates the long-term viability in the wild of these substances in other words they are hard biodegradation. In the industrial manufacture of explosives discharged a large amount of wastewater containing TNT. To treat these wastewater TNT, researchers often use .
