“…With the development of a very sensitive chemiluminescence method (Stauff and Jaeschke, 1975) SO2 in the lower stratosphere was detected. Already the preliminary measurements (Jaeschke et al, 1976) showed a remarkable result.…”

Absuact. In 1978-1980 nine aircraft flights to an altitude of up to 15 km were made over western Europe. Sulfur dioxide was measured with a sensitive chemiluminescence method consisting of separate sampling and analysis stages and application of a wet chemical fitter procedure (detection limit: 8 pptv SO2).The measurements performed in the upper troposphere and lower stratosphere lead to some unexpected results: (a) the meteorological conditions at the tropopause level have an important influence on the observed SO 2 mixing ratio; (b) between the 500 mb and the actual tropopause level the SO z mixing ratio is found to be < 100 pptv, and weak vertical gradients of SO 2 suggest only a small flux of tropospheric SO 2 into the stratosphere; (c) increasing SO: mixing ratios within the first kilometers of the stratosphere give strong support to a stratospheric source of SO2.In the light of improved one-dimensional models considering the vertical distribution of stratospheric sulfur compounds (Crutzen, 1981; Turco etal. 1981) it can be shown that the oxidation of organic sulfur compounds (e.g., OCS, CS2) seems to be a stratospheric source of SO2. Furthermore, the flux calculations based on the SO 2 mixing ratios measured at the tropopause level indicate that the contribution of tropospheric (man-made) SO: to the stratospheric aerosol layer is of only minor importance.

“…The reaction of sulphite with strong oxidants such as KMnO 4 in acid media is accompanied by a weak CL that has been reported extensively [26,27], it is proposed that the excited is the emitter and the emission spectrum is between 450 and 600 nm [28,29]. This weak CL reaction can be sensitized by not only several fluorescent, which is the energy-transfer mechanism [22,30] but also non-fluorescent compounds such as 3-cyclohexylaminopropane sulfonic acid (CAPS) [31], ibuprofen [32] and iproniazid [33] etc.…”

In this paper, a novel chemiluminescence (CL) method for the determination of tramadol has been developed by combining the flow injection technique and its sensitizing effect on the weak CL reaction between sulfite and acidic KMnO 4 . A mechanism for the CL reaction has been proposed on the basis of fluorescent and CL spectra. Under the optimized conditions, the proposed method allows the measurement of tramadol hydrochloride over the range of 0.04 -4 g/mLwith a correlation coefficient of 0.9995 (n = 8) and a detection limit of 0.01 g/mL (3σ), and the relative standard deviation for 2.0 g/mL tramadol (n = 11) is 2.1%. The utility of this method was demonstrated by determining tramadol hydrochloride in tablets and injections.

“…In 1975, Stauff and Jaechke [21] proposed that excited sulfur dioxide had been considered as the emitting species during the oxidation of sulfite by Ce(IV). This emission is based on an energy transfer between the excitated products of the Ce(IV) and sulfite, and it will give the intermediate product SO* 2 [22] which emits radiation in the spectral region 300-450 nm [23].…”
