PROBLEM TO BE SOLVED : To obtain a filter for recovering noble metal as extremely rare resources which drastically improves a recovering efficiency as compared to the conventional method and is excellent in a recyclability.
SOLUTION : In the filter, in which a metal adsorbent material is fixed to a basic material for filter with a binder resin, the metal recovering efficiency is improved by applying iodine-treatment to the filter. After recovering, the filter is treated with thiosulfate to separate and recover the noble metal, thereby obtaining the filter for recovering the noble metalwhich is excellent in the recyclability.
