It is expected that adsorbability of metal by wool will be changed when wool is degraded with alkali. The wool, treated with alkali for different length of time were used. The adsorption of Hg by wool was greatly increased when the wool was treated with alkali, while the adsorption of Ag by wool decreased, and that of Cu was kept constant, in the earier part of treatment. Hg curve had a peak in it. Cation exchange capacity of wool became greater as the time of treatment became longer, while anion exchange one was kept constant or less than that of non-treated. Adsorption of Hg or Ag by wool had a close relation to the lability towards alkalies of the disulfide groups is the cystine of the wool, but adsorption of Cu did not. The metal adsorbed by wool could be easily displaced by washing with acid.
