( DMA) than those of heavy meal ions with nitrite.Moreover, the intermediates of heavy metal ions with DMA can first release a proton, and then re-act with nitrous acid to form NDMA.This reaction is an exothermal process and its energy barrier is relatively low, from which it can be ...
As the reaction to form NDMA depends on the nitrite being protonated, Figure 1B shows the protonated nitrite concentration based on nitrite’s pKa, which is the negative log of the acid dissociation constant (Ka) value. The lower the pKa, the stronger the acid. For nitrite, the pKa value...
Development of these control strategies include characterizing nitrosamine precursor sources (including industrial sources), optimizing the removal of nitrosamines and their precursors through secondary nitrification/denitrification (NdeN) treatment, and across Full Advanced Treatment (FAT) consisting of ...
