Lead (Pb), brushite-metakaoiln geopolymer materials, Festuca rubra ABSTRACT Lead (Pb) is one of the most common environmental pollutants and high concentrations of this element can cause numerous symptoms of phytotoxicity. Inorganic amendments immobilize metal/metalloid ions and reduce their bioavailability in the soil by increasing pH or by adsorbing them. Adsorption mechanisms include chemical precipitation, ion exchange, and crystal growth. In this experiment, geopolymer materials were newly synthesized from a natural raw kaolinite clay with 2, 4, and 6 wt % (GPB2, GPB4, and GPB6) of pure brushite addition. Previous research has shown that brushite-metakaolin geopolymer materials can be successfully synthesized and that they have significant efficiency in removing lead ions from aqueous solutions.
