Research Abstract

To discriminate the sources of sulfur compounds in environment and discuss their behavior, isotopic measurement was carried out for the source sulfur which is generated by burning of fossil fuels and environmental sulfur which is included in air and suspended particulate matter. The results shows that sulfur in air is attributed to petroleum and sulfur in suspended particulate matter is attributed to coals. To collect air sample for the isotopic measurement, it takes about 50 days and is required to add absorbing solution once a week. In this project the new method for the collection of air sample was investigated by using activated carbon fiber. Sulfur dioxide in air sample was collected almost : it the efficiency of lO0%. This collection method is also able to shorten the collecting time. Simple qualitative analysis of inorganic components of suspended particulate matter was investigated by infrared spectroscopy. Sample is mixed with carbon and KBr and pressed before analysis. Several main inorganic components, sulfate, ammonium, silicate etc., are possible to be analyzed. Selenium isalso determined for coals and petrolenium to help the discussion to discriminate the sulfur sources. Coals contain more selenium than petroleum. The content of selenium in coals often shows more quantities than sulfur.
