PH Monitor of Air Pollutants, Research and Development of a New pH Recording Method and Instruments for the Recording of Acid and/or Basic Components Resulting from Launches of Rockets.
Abstract
Various methods and instruments were investigated for use in monitoring acidity and alkalinity of effluents resulting from launches of large rockets, especially those using solid rocket motors. An inexpensive, portable, battery-operated pH recorder was modified to monitor effluent or spilled pollutants during normal or catastrophic launches of large rockets. Two prototype pH monitors were constructed and used during firings of 15 solid rocket motors. The data from all recordings were reduced to read the fluctuations of concentrations and dose (exposure) in the air at various distances from the firings. All recordings were performed on strip charts. Tape recording was also tested; it is cheaper and lends itself for future computerized automation.
