This work investigated some characters of the ion-exchanger. The prepared
ion exchanger was carried out from the reaction of a waste rubber with
concentrated sulphuric acid, through the interchange of its counter ion with the
metal - ions of “Cu٢+
and Ni٢+“. Many observation were seen:
First, the capacity of the exchanger has greater value (٤ meq/g) in the case
of “Ni٢+” ion.
