The interaction between the OClO and In2O3 in the temperature range 260-350°C has been investigated, as well as the interaction of chlorine atoms with ZnO. Regularities in the change of In2O3 conductivity at OClO adsorption in the range of OClO concentration from 0.03 to 1 ppm have been revealed, as well as the regularities of ZnO conductivity change due to adsorption of chlorine atoms. Kinetics of In2O3 and ZnO conductivity change has been studied. Demonstrated is the possibility to apply the method of semiconductor sensors (SCS) to detection of atomic and molecular chlorine, as well as ClOx compounds in the atmosphere and to study the photochemical and heterogeneous processes with the participation of chlorine or its compounds.
