GREEN REMEDIATION: A CRITICAL EXAMINATION OF BIOCHAR’S HEAVY METAL ADSORPTION ABILITIES
AbstractBiochar can be used as an efficient and low-cost adsorbent for wastewater treatment as heavy metal pollution has become the serious issue for environmental pollution today. A number of studies have demonstrated effective removal of heavy metals from water by biochar. Several factors affecting the sorption tendency of biochar, feedstocks materials play a significant role. Depending on the biochar type, heavy metals can be removed by different methods such as complexation, physical sorption, precipitation and electrostatic interactions. In recent years, ample method for heavy metal removal from wastewater has been extensively studied. This paper reviews the recent methods that have been used to treat heavy metal removal from wastewater and evaluates these techniques. These techniques include ion-exchange capacity, adsorption, membrane filtration, coagulation-flocculation, flotation and electrochemical methods. From literature review it is evident that ion-exchange, adsorption and membrane filtration are the most recent studied for the treatment of heavy metal wastewater.
