Abstract :
The control of air quality is of great importance, in particular for the protection of the workers who can be exposed to toxic gas. The present work reports the development of new chemical sensors for the detection of halogenated gases. These sensors are based on the use of nanoporous matrices doped with cationic surfactants and acting as sponges to trap the targeted pollutants. These chemical sensors can be used for the detection of chlorine Cl2 or nitrogen trichloride NCl3 at ppb level.
