英文摘要 | it was reported on the elimination of interfering absorption of btx. the absorption of o-2 includes different absorption bands, which change differently when the partial pressure of oxygen is varied. these cause the nonlinear absorption of o-2 and the observed band shape to vary with the column density of o-2 the absorption ratios of molecular absorption in each of the herzberg hands and dimer absorptions, as well as the contribution to the correction error of molecular absorption, are studied based on the characteristic of these absorption bands. the optimized way, to eliminate the interfering absorption is obtained in the end and the effectiveness of using interpolation proposed by volkamer et al. to remove o-2 absorption is proved again. as to o-3 and so2, the effect of the thermal effect of characteristic spectra on the elimination error of their absorption is studied. solutions to these problems are discussed and demonstrated together with methods to optimize the interpolation of spectra. as a sample application, differential optical absorption spectroscopy (doas) measurements of btx are carried out. results show a low detection limit and the good correlation with point instruments are achieved. all these prove the feasibility of using spectral interpolation to improve the accuracy of doas measurements of aromatic hydrocarbons for practical purposes. |
