ABSTRACT:
An alkali metal iodide and phosphoric acid are homogeneously supported on an activated carbon honeycomb, in respective amounts of 0.015 to 1.5 mg atoms as iodine and 1.4 to 7.0 mg equivalents per gram of activated carbon. The alkali metal iodide is potassium iodide. When both the chemicals are supported on activated carbon in amounts respectively within the above ranges, homogeneous supporting of phosphoric acid with the alkali metal iodide becomes possible without causing any decrease in adsorption and elimination capacities. A number of malodorous and harmful components such as nitrogen-containing compounds and sulfur-containing compounds can be efficiently removed with one kind of activated carbon over a long period of time. The activated carbon adsorbent thus obtained can be used for various deodorization purposes and in exhaust gas treatment, and is particularly suited for use in toilet deodorization and in gas treatment in closed spaces, for example in refrigerators.
