Copper adsorption using phosphoric acid-based geopolymers

Heavy metal pollution has been a recent topic and low cost adsorbents have been a trend to treat and remove heavy metals from waste water. The discovery of geopolymers has been a breakthrough in the field due to its amorphous and porous structure. The objectives of this research are to synthesize an...
