To detect sub-ppm levels of dry HCl gas, spectral changes of tetraphenylporphine dispersed in ethylcellulose were examined in the visible region. The Soret and Q-bands of free base tetraphenylporphine are sensitive to sub-ppm levels of HCl with a good reversibility and insensitive to NH3, Cl-2, NO2 and NO at room temperature.

Abstract
To detect sub-ppm levels of dry HCl gas, spectral changes of tetraphenylporphine dispersed in ethylcellulose were examined in the visible region. The Soret and Q-bands of free base tetraphenylporphine are sensitive to sub-ppm levels of HCl with a good reversibility and insensitive to NH3, Cl-2, NO2 and NO at room temperature.File in questo prodotto:
