Vapor phase hydrogen peroxide (VPHP) nowadays finds more and more applications especially as a biodecontamination agent for enclosed areas. Although this oxidizing agent logically offers a potential for the degradation of hazardous chemical contaminants, the information on the utilization within this area is very limited. The main objective of this study was to examine in detail the influence of basic operational (temperature, concentration of VPHP, relative humidity, condensation) and other conditions (e.g. amount of contaminant, the effect of UV radiation) on the efficiency of the VPHP process for the degradation of the selected model substance, i.e. 4-(dimethylamino)benzaldehyde. For this purpose, a series of different VPHP wet decontamination cycles (with a visible condensation) were carried out and compared.
