| Summary: | Rapid development of advanced technology in Malaysia gave
impact increasing in the accumulation of heavy metal every day in our
daily life through wastewater. Long term exposure of human bodies to
heavy metals susceptible to receives various infections and diseases. From
an environmental and economic perspective, adsorption is acceptable
process that can be applied in wastewater treatment. However, usage of
activated carbon most acknowledged and costly adsorbents lead people to
find an alternative to activated carbon. Several studies of physical
properties of geopolymer make them gain attention to replace an activated
carbon in the treatment of heavy metal. This paper review adsorption of
heavy metal by using geopolymer.
