Summary: | A metal element adsorbent in the form of a hydrogel prepared by treating a condensed tannin with a base, in the presence or absence of an aldehyde so as to avoid precipitation of cross-linked tannin and produce a hydrogel. The inventive adsorbent exhibits high adsorption properties for metal elements and a low flow resistivity when used in a packed column. Methods for use of the inventive adsorbent are disclosed. |
