- •
Novel regenerable NH4+ sorbent was developed: metakaolin geopolymer.
- •
Geopolymerization significantly improved the NH4+ removal capacity of metakaolin.
- •
Surface area, pore width and volumes increased as a result of geopolymerization.
- •
Geopolymer was approx. 46% more effective than clinoptilolite–heulandite zeolite.
- •
Landfill leachate field test confirmed the practical applicability of the results.
