Figure 2 13 C-NMR study of the reaction between NH 4 HCO 3 and H 2 O 2 . (a) 13 C-NMR spectrum showing the presence of peroxymonocarbonate ions (HCO 4 - ) at 159.5 ppm and bicarbonate ions (HCO 3 - ) at 161.5 ppm in an aqueous gel simulant mixture containing 7.5% (w/v) NH 4 HCO 3 , 15% (w/v) of ethylene glycol (EG), and 4 % (w/v) H 2 O 2 . (b) Plot of the concentrations of HCO 4 - and HCO 3 - against the concentration of H 2 O 2 in gel simulant mixtures comprised of 7.5% (w/v) NH 4 HCO 3 , 15% (w/v) of EG, and variable 0 to 8% (w/v) H 2 O 2 .
Raw data used for the graphing of Figure 2 in the manuscript. Depicts the 13 C-NMR study of the reaction between NH 4 HCO 3 and H 2 O 2 . Files include t
