Abstract The speciation of NO2, NO, and N2O gases formed from the dissolution of copper in nitric acid is measured and characterized using Fourier-transform infrared (FTIR) spectroscopy. This study describes analysis of the gas phase species formed and ingrowths of their concentrations as a function of time. Acid concentrations range from 14 to 4 M and the NO2, NO, and N2O are analyzed using FTIR between 1585 and 2209 wavenumbers. The concentrations of the gases range from 0 to 230 ppm and change over time and as a function of acid concentration.

使用 FTIR 光谱分析硝酸/水溶液中铜溶解的 NOx 形态

摘要 使用傅里叶变换红外 (FTIR) 光谱测量和表征了由铜在硝酸中溶解形成的 NO2、NO 和 N2O 气体的形态。本研究描述了对形成的气相物种及其浓度随时间向内生长的分析。酸浓度范围为 14 至 4 M，并且使用 FTIR 分析了 1585 至 2209 波数之间的 NO2、NO 和 N2O。气体的浓度范围从 0 到 230 ppm，并且随时间和作为酸浓度的函数而变化。
