| Abstract: | In this study, we indicate the working principle and the limits of utilization of an electrochemical chlorine gauge and we demonstrate its excellent specificity. This gauge allows us to measure continuously the partial pressure of chlorine in the atmosphere. During our experiments, it has been set on a sampling loop, which is itself connected to the 2-m3 atmospheric simulation chamber, but we can also use it in the field.We have been able to follow, with precision, the evolution of an identical initial concentration of chlorine in air, with and without irradiation, for different humidity levels and in the presence of other pollutants. |
