The geopolymer technology provides an alternative good solution for the utilization of industrial waste and the preservation of primary minerals to produce an economically valuable product that can be used for several purposes. This review summarizes the preparation, the structure modifications and functionalization of geopolymers for adsorbing purposes. The mechanical performances of the geopolymers (compressive strength, flexural strength, durability such as resistance to sulfate, acid, thermal effect) are the primary concerns that depend on the chemical composition.
