Abstract
A chelate-forming fiber which has, in a fiber molecule, a group having an amino group and at least two hydroxyl groups bonded to carbon (preferably a group represented by the formula (1) described below), and has a capability of forming a chelate with metalloid elements including boron and germanium and compounds thereof, and which can be easily incinerated and can be prepared in a simple and safe manner at low cost; and a process for preparing the same; and a method for capturing metalloids or compounds thereof using the chelate-forming fiber are disclosed. ##STR1## (wherein G represents a sugar alcohol residue or a polyhydric alcohol residue, and R represents a hydrogen atom, a (lower) alkyl group, or G (G is as defined above and may be a group identical with or different from the above G).)
