| Abstract |
A sample cell has been designed and built to contain hot H2SO4 vapor for spectroscopic analysis. The cell is heated to between 190 and 250C by an electric furnace designed specifically for use with the sample cell. A small bulb connected to the main compartment of the sample cell contains liquid H2SO4. The partial pressure of the H2SO4 vapor is controlled by regulating the temperature of the liquid H2SO4, which is at lower temperature than any other part of the cell that is in contact with the vapor. Transmission curves have been scanned for a variety of samples over the 7.8 micrometer - 12.8 micrometer region with spectral slitwidths between 0.5/cm and 4/cm. At wavelengths of maximum absorption near 8.2 micrometer and 11.4 micrometer, the absorption coefficient is approximately 0.0004/(ppm - meters). During the early part of the present contract, EPA scientific personnel investigated the complex chemical reactions involving SO3 that occur in the stacks of stationary sources. The results of this investigation indicated that the typical effluent probably contains more H2SO4 than SO3. Thus, it was decided that the need for an H2SO4 monitor was greater than that for an SO3 monitor. |
