Evaluation of ion exchange material from sulfonated polystyrene waste synthesized for removal Cr3+ from aqueous solution by column experiment

The paper aims to study the effect of operatiing conditions in the column experiment with the ion exchange material which was prepared in optimum synthesized conditions. Polystyrene waste from disposable food packaging was dissolved in cyclohexane and sulfonated by sulfuric acid to synthesize cation exchange materials which were applied to remove Cr3+ in water by the ion exchange principle.
