Electrochemical Generation of Pollutant Standards

Source

Six common ambient air pollutant species (ozone, nitric oxide, chlorine, carbon monoxide, sulfur dioxide, and hydrogen sulflde) have been electrolytically generated at the parts-per-billion to parts-per-million level in a scrubbed ambient air carrier. Theoretical background and practical aspects of this technique are discussed, and the difference in pollutant output to that expected theoretically is reviewed. Under the conditions of the work reported, the desired theoretical output was not achieved. As a result, this technique does not appear feasible as a primary technique for the production of these species. However, the approach may serve as a convenient, low-cost means to produce secondary or working standards for the calibration of ambient level air pollution analyzers.
