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).
