Abstract
The present invention provides a novel fibrous chelate-forming material to which a capability of forming a chelate with metal is imparted by introducing a specific acyl group represented by the following general formula [1] or [2], and also discloses a novel process for producing a chelate-forming fiber, a process for sequestering with the same, and a filter capable of simultaneously removing impurities and metal ions in a fluid is imparted using the chelate-forming fiber. ##STR1## [wherein each symbol is as defined in the specification.]
