| Description: |
AbstractAmmonium removal from explosive agent residues containing mining effluents represents a challenge, especially in cold climate. As environmental agencies are demanding ammonium removal at mine sites in e.g. Finland and Sweden, new methods are required. Natural zeolites are the most studied sorbents for ammonium removal and one promising material is a mining industry byproduct, analcime. In this study, the ammonium removal capacity of analcime was improved by using geopolymerization. Four types of geopolymers were prepared and tested as an ammonium sorbent by using model solutions at different temperatures. Finally, the material could be regenerated or utilized e.g. as a fertilizer. see all
