Meanwhile, the ion concentrations depicted in Fig. 4.15 show that with
increasing the molar ratio within 0.7 - 1.0, a particularly low the NO
3
concentration appears and varies slightly, while the NO
2
concentration increases.
These observations occur because the increasing NO
2
content takes part in the
redox reactions with tetravalent-S components. After the molar ratio exceeds 1.0,
the NO
3
and NO
2
concentrations rapidly increase and decrease with the molar
ratio, respectively. These findings are attributed to the fact that with the excessive
O
3
existence, the generated N
2
O

reacts with H
2
O to produce a considerable
dosage of nitric acid through the aforementioned reactions in Eqs. (4.12) - (4.14),
