Ammonia Removal From Water Using Cationic Materials Ku-2-8 and Dowex Mac-3

Year: 2025

Type: article

Abstract: In this work, it is shown that theareighest efficiency of ammonium extraction from water using cationites KU-2-8 and DOWEX MAC-3 is achieved when they are used in their acidic form. It has been established that hardness ions, namely calcium and magnesium ions, complicate the process of ion-exchange ammonium extraction, since these cationites have a higher selectivity for hardness ions. The highest level of regeneration of cationite KU-2-8 was found by using acid solutions compared to sodium chloride solutions. The use of phosphoric and nitric acid solutions for regeneration will allow further use of regeneration solutions for fertiliser production.
