30/11/2011, · In the second setup, a carbon steel cathode and DSA ®. of DSA ® ,Ti,/TiO 2-RuO 2-SnO 2 were used, in a solution ,containing, NaCl, which produced strong oxidizers such as HOCl and Cl 2. These promoted degradation of BTEX and phenol at different flow rates. The Zn +2 was removed by electrodeposition or by the formation of Zn(OH) 2 due to the increased pH.

First, 0.1 g DTT (calcined at 450 °C) was impregnated in 5 ml saturated iron nitrate solution. After 5 h, it was washed with deionized water in a Buchner funnel and dried at 80 °C. The ,Fe, 2 O 3 @DTT catalyst was obtained after calcination at 150 °C. The synthesis of ,Fe, 2 O 3 @HPS was similar to that of ,Fe, …

7/4/2009, · When ,Fe, 2+ ions were added to the process, no change was observed in its efficiency. Such high values in the mineralization of these compounds are important because of the role of nitrotoluenes as intermediates in the pharmaceutical and dye industries as well as their role as precursors of TNT. Another ,wastewater, pollutant is dimethyl sulfoxide (DMSO).
