Abstract
To detect sub-ppm levels of dry HCl gas, spectral changes of tetraphen ylporphine dispersed in ethylcellulose were examined in the visible re gion. The Soret and Q-bands of free base tetraphenylporphine are sensi tive to sub-ppm levels of HCl with a good reversibility and insensitiv e to NH3, Cl-2, NO2 and NO at room temperature.
