High-sensitivity Sensors for Monitoring of Lead Atmospheric Corrosion

Popis výsledku v původním jazyce

Thanks to the specific sensitivity of lead to volatile organic compounds (VOC), it is possible to use lead as an indicator of contamination of the indoor atmosphere of depositories of archives and museums where VOCs are typical pollutants. The classification of corrosion aggressiveness of indoor environments based on the determination of the corrosion rate of reference metals is given by the standard ISO 11844-1 which was recently supplemented with lead. Established techniques for determining the corrosion rate of lead are not sensitive enough to monitor the corrosive aggressiveness of the indoor environment. The aim of this project was to develop a promising, highly sensitive method for measuring the corrosion rate of lead in the indoor atmosphere. Innovative highly sensitive electrical resistance lead sensors have been developed for this purpose. At the same time, a low-cost alternative sensor working on the electrochemical principle was developed employingsingle frequency impedance measurement for indicating variations of surrounding air aggressivity. The sensitivity of such a sensor was observed to behigher than that of the traditionalelectrical resistance sensors.
