Abstract
The present invention provides a getter material comprising an adsorbent active substance with a specific surface area of 5˜40 m2/g. Also, the present invention provides a method for manufacturing the adsorbent active substance comprising the steps of: (a) selectively eluting cations by the acid processing of any one of calcium carbonate, barium carbonate, magnesium carbonate, aluminum carbonate, or strontium carbonate; (b) extracting the eluted cations; and (c) calcining any one of calcium carbonate, barium carbonate, magnesium carbonate, aluminum carbonate, or strontium carbonate from which cations have been extracted.
