Abstract
PURPOSE:To prevent the discoloration by enclosing a plated decorative article such as necklaces and earrings in a closed vessel along with an adsorbent having desulfurizing activity. CONSTITUTION:An aq. soln. contg. an alkaline substance such as sodium hydroxide and potassium hydroxide is absorbed in zeolite, activated carbon, etc., and then dried to form an adsorbent. The alkaline substance in such an adsorbent exhibits strong reactivity to gaseous sulfur dioxide and hydrogen sulfide, adsorptive reactivity is also exhibited by the porous material, and hence the desulfurizing activity is remarkably increased. A decorative article is enclosed in a closed vessel along with the adsorbent packed in a small bag. In addition, a dehumidifying agent is preferably enclosed in the vessel. By this method, extremely effective preserving environment is formed, and the discoloration of the decorative article can be prevented over a long period.
