Environmental pollution and healthy problems of industrial wastewater, as well as corrosion of boilers have brought great costs and problems of human society. Utilization of chemical materials can resolve these problems. Nowadays, Diethyl hydroxyl amine is of high interest and has many applications, including decolorization and oxygen scavenging. In this paper, we synthesized DEHA using nano SiO2 as catalyst. The decolorization property of DEHA was evaluated in methylene blue and malachite green degradation as two samples of dye effluent. Also, oxygen scavenging by DEHA was studied successfully.
