Abstract
The reaction of cyanogen chloride (CK) gas and oxygen on Whetlerite charcoals has been studied in a specially-designed chamber. Short-lived intermediate gas phase species are detected by a mass spectrometer located close to the Whetlerite surface. After the reaction, the specimens are transferred to an X-ray photoelectron spectrometer (XPS) for surface analysis. CK was flowed over several charcoal adsorbents - with and without metal impregnants. Short-lived reaction products such as CO, HOCN, HCl and CN could be detected. Injection of oxygen into the reaction along with CK results in a decrease in CK concentration and an increase in CO. The effect varies with the type of adsorbent. Reaction with CK results in changes to the surface chemistry of the metal impregants: for example, Cu(II), originally present as CuO or Cu(OH)2 reduced to Cu2O). TRUNCATED
