The removal of toxic metals from liquid effluents by ion exchange resins. part VI: Manganese(II)/H+/Lewatit K2621

In this sixth part of the series, Manganese(II) was removed from aqueous solutions by the cationic exchange resin Lewatit K2621. The investigation was performed under various experimental conditions such as the stirring speed associated with the system, aqueous pH, temperature, resin dosage and the...
