Abstract
Four techniques for determination of water soluble sulfate in atmospheric samples were compared including the barium sulfate turbidimetric method, the Brosset (barium-Thorin) method, the automated barium-methylthymol blue procedure and a microchemical (barium-dinitro-sulfanazo III) colorimetric method developed at the Air and Industrial Hygiene Laboratory. These, in turn, were compared to x-ray fluorescence for determination of total sulfur, obtained independently at the Environmental Protection Agency's Research Triangle Park Laboratory. The parameters studied included precision and accuracy employing standard solution and ambient air samples, and the influence of twelve potential interferents. The ambient air samples studied were collected at different locations throughout the U.S. so that the influence of different particle matrices could be evaluated. As supplementary objectives, analyses of particulate matter samples collected simultaneously on high volume and low volume glass-fiber filters, with and without size segregation, were compared. Results of the study are presented. (Portions of the document are not fully legible.)
