The anionic and mixed exchangers were prepared from rubber waste, which was
treated previously with chlorine or bromine or sulfuric acid, by reaction with ammonia or
pyridine.
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.
