Abstract
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.
Highlights
Nowadays, management of waste and quality of water is two of the important proposition in human life
Accretion of technologies in urbanization and industrialization lead to increase in percentage accumulation of waste all around the world and release of heavy metal in the water streams
These harmful heavy metals are an output from varieties activities such as industrial, waste disposal, agricultural and others
Summary
Management of waste and quality of water is two of the important proposition in human life. Accretion of technologies in urbanization and industrialization lead to increase in percentage accumulation of waste all around the world and release of heavy metal in the water streams. These harmful heavy metals are an output from varieties activities such as industrial, waste disposal, agricultural and others. Accumulation of heavy metal in wastewater streams acts against human bodies and cause to death. Technologies used in the treatment of wastewater include chemical precipitation, ion-exchange, adsorption, membrane filtration, coagulation-flocculation, flotation and electrochemical [13]. Adsorption is one of a common treatment applied in the heavy metal removal involves adsorbents such as undoubtedly activated carbon. Studies of low cost adsorbent are intensively gain an attention to the scientist were usually waste product from industrial, agricultural and food production which produced abundantly [6]
