Heavy metals and organic compounds are usually presented in the water causing great interest due to environmental concerns. While the first ones are well regulated and their toxic effects on health and the environment are well known, the second ones are not completed regulated and their toxic effects are still not well understood. Due to primary and secondary treatments are not able to completely remove them advanced tertiary treatments are required to improve the quality of the municipal effluents into sensitive receiving water bodies. Among advanced tertiary treatments, adsorption onto granular activated carbon (GAC) has been proven to be a viable technique to remove because of its simplicity, efficiency, and no chemical transformation of compounds, but its main drawback of GAC applications is the need to properly treat and dispose of the spent carbon due to its loss of adsorbent capacity. For some years biochar has been studied as an alternative adsorbent because of its chemical-physical properties such as high specific surface and porosity and it is cheaper than GAC. Biochar is a solid carbonaceous material obtained from the pyrolysis of biomass such as plant and animal waste, and activated sludge, therefore, biochar plays an important role in the sustainable treatment of waste. Even if its main use is as a soil improver, many researchers demonstrated its high removal capacity of heavy metals and organics from water. Most of those studies used biochar produced at scale lab, however few studies used commercial biochar as adsorbent. Hence, this review aims to analyses those studied in which commercial biochar was used as an adsorbent to remove heavy metals and organic compounds considering and the relationship with its properties. |
