METALLKOMPLEXFORMENDE FASER, PROZESS ZU DEREN HERSTELLUNG, UND VERFAHREN ZUR KOMPLEXIERUNG VON METALLIONEN MIT DIESER FASER

摘要

The present invention provides a metal chelate forming fiber in which a reactive functional group in a molecule in the surface of the fiber is substituted with an acyl group represented by the following formula Ä1Ü: (where R<1>, R<2>, and R<3> respectively are a lower alkylene group, and n is an integer of 1 to 4.) The present invention also provides a method for preparing the fiber, and a process for treating waste water using the fiber where metal ions contained in the waste water are allowed to be captured by the acyl group.
