Abstract:

The purpose of the research was to study methods for the vapor deposition of metals and metal salts into the pores of activated carbons, and evaluate properties imparted to the carbons for toxic gas removal by this method of impregnation. A successful method for the vapor deposition of copper within the carbon pores using copper acetylacetonate as the reactant was developed and samples containing 8, 4, 2 and 12 copper by weight were prepared using PCC grade CWS carbon. Tests were run on these samples to determine their characteristics. A technique was developed for the vapor impregnation of activated carbon with chromium trioxide through the ammonolysis or hydrolysis of chromyl chloride which had previously been adsorbed on the carbon. Samples were prepared by this method on carbons which had already been impregnated with copper. Analytical tests performed on the samples showed that chromium was present on the carbon in the 6 oxidation state and copper in the 2 state. The emission spectrograph analysis indicated the metals were present in the predicted concentration range. Author
