Resumo
The absorption of N2O from an air flow in various aqueous solutions at 293–298 K was studied. The maximal N2O absorption under the experimental conditions is reached for water (~22–24%) and saturated solution of K2Cr2O7 in concentrated H2SO4 in the presence of Al2O3 and without it (~34 and ~30%, respectively). In concentrated HNO3 and NH4OH solutions and in 1.0 M NaOH and N2H4·nH2O solutions, the degree of the N2O absorption varied from ~7.5 to ~11.5%. Similar degree of absorption was obtained with 0.5 M (NH2)2CO (~11%). In the other solutions tested, the degree of the N2O absorption did not exceed ~4.0%.
