Аннотация:Findings from a study of the N2O absorption from an air flow in various aqueous and organic solutions at 293–298 K were reported. The maximum N2O absorption reached under the experimental conditions for water (~22–24%) and a saturated solution of K2Cr2O7 in concentrated H2SO4 with and without Al2O3 (~34 and ~30%, respectively) was determined. In concentrated HNO3 and NH4OH solutions, as well as in 1.0 mol/L NaOH and N2H4⋅nH2O solutions, the degree of the N2O absorption varied within a range from ~7.5 to ~11.5%. A similar value of absorption was also found in 0.5 mol/L (NH2)2CO (~11%). In other solutions,the degree of the N2O absorption was not more than ~4.0%. In the studied organic solutions, the degree of the N2O absorption was found to be less than ~12%.
