PURPOSE: To obtain a removing agent capable of adsorbing and removing the arsenic compound contained in gas or a liquid with a high removal ratio, by constituting the same from activated carbon, and a copper group compound and a chromium group compound supported by said activated carbon. n CONSTITUTION: The titled removing agent consists of activated carbon, and a copper group compound and a chromium group compound supported by said activated carbon and the support amount of said copper group compound is set to 0.5W30wt% as a copper group metal while that of said chromium group compound to 0.5W20wt% as a chromium group metal. Activated carbon, which supports the copper group compound and the chromium group compound in the above mentioned ratio, has a high removal ratio of arsenic hydride such as arsine and shows a high adsorptive removal ratio even to sulfide, oxide or halide of arsenic and can adsorb and remove an arsenic compound contained in gas and a liquid with a high removal ratio. n COPYRIGHT: (C)1985,JPO&Japio |
