Effect of Aluminium Powder on Kaolin-Based Geopolymer Characteristic and Removal of Cu.

This current work focuses on the synthesis of geopolymer-based adsorbent which uses kaolin as a source material, mixed with alkali solution consisting of 10M NaOH and NaSiO as well as aluminium powder as a foaming agent. The experimental range for the aluminium powder was between 0.6, 0.
