| titleOfInvention | Electrochemical air pollution monitoring device and method of use thereof |
| abstract | An electrochemical monitoring device has been provided for measuring air pollutants. A thin layer of electrolyte solution is exposed on one side to the atmosphere and on the other side to a mercury pool electrode. Electrochemical reactions which take place at the mercury electrode surface due to the presence of certain pollutants alter the current flow through the mercury pool at a given voltage, thereby providing an indication of the amount of the particular pollutant under study. Since certain important pollutants undergo electrochemical reactions with mercury at different potentials and other pollutants react chemically with mercury, several methods of operation can be used. In one method, selective current responses are obtained for the detection and determination of different pollutants by varying the mercury electrode potential. In a second method, the products of chemical or electrochemical reaction are accumulated in the thin layer of solution or at the electrode surface, and are periodically determined by current coulometric measurement. These two methods can be used jointly and supplement each other. |
