  • SULFUR DIOXIDE 131

    Conductimetric analysis measures the increase in conductivity as sulfur dioxide is absorbed into a hydrogen peroxide solution. This method has also been used to measure sulfur dioxide in the air (Adams et al. 197 1). Conductimetric analysis is popular because it of its high sensitivity, fast response, minimal maintenance, and simple operation.

    The para -rosaniline hydrochloride (PRA) dye -based manual method (P. W. West and G. C. Gaeke, Anal. Chem ., 1956, 28, 1816) is widely used for sulfur dioxide measurements in the atmosphere, particularly in developing countries. In this investigation, the properties of a less costly, rosaniline hydrochloride (RA) dye were found to be similar to those of the PRA dye, and showed no significant variation in atmospheric SO 2 determination.

The interaction energies for adsorption of SO 2 are about −166 and −277 kJ mol −1 whereas the corresponding energies for O 3 are −362 and −396 kJ mol −1 for configuration A and B, respectively. These observations show that functionalized B 12 N 12 are highly sensitive toward SO 2 and O 3 molecules.

    Abstract. In recent years in a few Chinese megacities, fog events lasting one to a few days have been frequently associated with high levels of aerosol loading characterized by high sulfate (as high as 30 μg m (-3)), therefore termed as haze-fog events. The concomitant pollution characteristics include high gas-phase mixing ratios of SO2 (up to 71 ppbv) and NO2 (up to 69 ppbv), high aqueous phase pH (5-6), and smaller fog droplets (as low as 2 μm), resulting from intense emissions from

    Fluorescence spectroscopy (also known as fluorimetry or spectrofluorometry) is a type of electromagnetic spectroscopy that analyzes fluorescence from a sample. It involves using a beam of light, usually ultraviolet light, that excites the electrons in molecules of certain compounds and causes them to emit light; typically, but not necessarily, visible light.
