A new ion exchanger has been prepared from syrian petroleum coke (S. P.
C) of high sulphur content. Preparation of this ion exchanger was carried out
by simple treatment of S. P. C with oleum at room temperature followed with
statical ion exchange
in aqueous sodium chloride solutions.
The First, SPC ion exchanger with granular structure resulted from
reacting 20 gr of the SPC granules with 20 ml of oleum. Where as a friable ion
exchanger was produced when 40 ml of oleum were used in the process.
The adsorption capacity of the two SPC ion exchangers was found out to be
100 mgeq and 170 mgeq respectively.
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.
