Document Type and Number:

WIPO Patent Application WO/1998/048098

Kind Code:

A1

Abstract:

A new fibrous chelate-forming material prepared by introducing specified acyl groups of general formulae (1) and (2) into fiber molecules to impart the function of forming a chelate with a metal to the molecules; a new process for thus producing the chelate-forming material; a process for sequestering with the fibers thus treated; and filters produced from the chelate-forming fibers and capable of removing insoluble impurities and metal ions from a fluid at the same time. In said formulae, symbols are each as defined in the description.
