The rapid development of advanced technologies in the world increases the impact on the daily accumulation of heavy metals in daily life through wastewater. Long-term contact of the human body with heavy metals leads to a variety of infections and diseases. From an environmental and economic perspective, adsorption is an acceptable process that can be used in wastewater treatment. . However, the use of accepted and costly activated carbon adsorbents has led them to look for a suitable alternative to activated carbon. Many studies have been conducted on the physical and chemical properties of geopolymers, which have attracted attention to the replacement of activated carbon in the treatment of heavy metals. In this paper, based on scientific evidences, the absorption of heavy metals using geopolymer is investigated.
