Critical Studies of the Asia-Pacificf SO.=) or lower can be expected. When a heater was inserted upstream of the diffusion stripper, the response to H.SO. decreased to zero between 70 and 135°C and to (NH.).SO. between 140 and 220°C. These phenomena result from the conversion of the aerosol sulfur to H.SO., SO., and SO. gases which ar
