Abstract
The present work involve preparation of some new polymeric extractors by reaction of polyurethane foam with some organic analytical reagents (grafted Congo Red foam, grafted methyl green foam) loaded foam with bathophenanthroline, loaded foam with Neocuprione loaded foam with Aliquat336) and (Diamino uracil). Also, the different parameters affecting the extraction were tested. Finally, Apart is introduced on reviewing many literature data dealing with separation and preconcentration techniques. It is interesting to define and fix the experimental condition to prevent any obstacles to occur.
