The need for economically efficient wastewater treatment arises with the continuous growth of various industries. To address this concern, various studies turn to bioadsorbents like magnetic biochar as an alternative treatment for heavy metal contaminated waters. In this study, the various characteristics and performance of magnetic biochar in the removal of heavy metals were investigated. This was done by reviewing numerous studies produced between 2009 and 2020 relevant to the topic. It was found that the main factors affecting metal sorption were pyrolysis temperature, solution pH, pHpzc, and surface functional groups. However, the trends vary depending on the heavy metal. This study also identified the adsorption isotherms, kinetic models, and adsorption mechanisms of each heavy metal via magnetic biochar. Further studies investigating the individual effects of magnetization and feedstock type should be conducted in order to optimize magnetic biochar performance. Application on actual wastewater is also recommended.
