Abstract
The objective of this investigation was to develop a carbon monoxide detecting substance to be used in badges that respond quickly to carbon monoxide by a definite color change. Carbon monoxide devices that use silica-gel were impregnated with metal salts. When carbon monoxide is present the detection gel (with the treated silica-gel) changes from yellow to blue-green or blue. The detection gel regenerates, that is, returns to its original yellow color within 4 to 24 hours after removal from air containing carbon monoxide. The detection gel exhibits a threshold response that can be adjusted over a wide range of carbon monoxide concentrations, typically from 50 to 500 ppm in air.
