Direct spectroscopic methods are not hampered by wall losses, are highly specific, have a potential for real time detection and offer the possibility to measure several species simultaneously in one experiment. This is demonstrated for the determination of NH 3 , NO and SO 2 in ambient air by...
Study on the Removal Efficiency of SO2 Gases by a Wet Type Electric Precipitator The experimental device for the removal of SO2 in flue gases is a wet type cylindrical electric precipitator with liquid irrigated glass wall (positive electrode) and a wire at its center producing a corona discharge...

The most convenient solvent for the preparation of 1and 2is SO2ClF but for 3and 4it is SO2. The reactions are complete after about three days stirring at −30 to −40 °C. The salts are stable for weeks in solution at −40 °C and stable for a few hours at RT in the solid...
For measurement of sulfur dioxide (SO2) in ambient air, the United States Environment Protection Agency (US EPA) had recommended the PRA dye-based colorimetric method as a reference technique. The method has been developed and applied in many countries for a longtime; however information regarding...
