M. Wilk et K. Kozlowski, The effect of nitrous acid on the efficiency of nitrogen oxides absorptionin nitric acid water solutions, INZ CHEM PR, 22(3E), 2001, pp. 1483-1488
A review of literature reports and results of our investigations concerning
the effect of nitrous acid, present in nitric acid solution, on the effici
ency of nitrogen oxides absorption have been presented. It was found that t
he reduction of nitrous acid concentration in the solution gave substantial
increase of nitrogen oxides absorption efficiency.
