Influence of sulfite on radiolytic conversion of nitrate and nitrite in dilute aqueous solutions

“…For the removal of volatile nitrogen compounds, the irradiated solutions were kept in a thermostat at 50 °C for 40 min before the analysis. Computer simulation with the use of kinetic data [6][7][8] and an algorithm 9 was applied to explain the basic radiolysis stages.…”

Towards a Consistent Chemical Kinetic Model of Electron Beam Irradiation of Humid Air

“…As a first step, the major loss pathways of HNO 3 were determined and considered as possible sinks for HOONO. Eight HNO 3 Langevin-Gioumousis-Stevenson rate constants [47] were calculated for the cation-HO-ONO reactions. The anion-HOONO rate constants were estimated from the average anionmolecule rate constant to be 1 9 10 -10 cm 3 s -1 .…”

“…There is a long history of investigating the use of electron beams for removal of NO x and SO 2 from power plant emissions [1][2][3]. The key to removal of these species is believed to be reaction of NO 2 and SO 2 with hydroxyl radicals (OH), leading to nitric and sulfuric acids [4].…”

On the mechanism of formation of intratrack yields of water radiolysis products upon irradiation with fast electrons and positrons: 1. Model formulation

“…However, for blobs and ionization cylinders in which the number of particles is large, the equations of inhomogeneous chemical kinetics (deterministic approach) give reasonably good results. Nonetheless, despite of considerable efforts, the stochastic theory gave satisfactory agreement only with a part of experimental data, namely, with the data on the time kinetics of the decay and buildup of water radiolysis products [11][12][13]; progress in the joint description of the time development data and concentration dependences of yields turned out to be very modest [14,15].…”
