In this research, we headed towards the utilization of waste rubber vulcanizing (car wheels) and it by transforming it into cationic exchanger without precious material consumption or complex equipment. The waste was ground into small pieces except the layer containing the steel wires in order to reach a degree of smoothness that enables us to deal with the rubber waste and obtain the greatest degree of homogeneity, then it was treated with sulfuric acid and benzene to insert its aromatic benzene rings into the double bonds found in polybutadiene and polyisoprene, which represents about half of the wheel weight and it was treated at the normal temperature for 7 days.In the next stage. The aromatic rings resulting, it was sulfonated by oleum for five hours at 110 oC and get a cationic exchanger. Some of the chemical-physical properties of the prepared exchanger were studied (acid capacitance, exchange capacitance, distribution coefficients, bloating water, and stability of the exchanger towards reactivation processes). The acidic capacity reached the value (5.8 meq/g), the bloating water reached the value (0.63 gH2O/g) for the acidic formula and the value (0.70 gH2O/g) for the salt formula, and determined the exchange capacitances for copper and nickel cations at different sizes and concentrations. It was found that the exchange capacitance increases with increasing volume and concentration. The prepared exchanger has good acidic and exchange capacity, which allows it to be used to purify industrial water from heavy metal cations, as well as its chemical and mechanical stability towards reactivation processes.
