Recent Trend and Evaluation of Bio-assisted Adsorbents for the Removal of Emerging Pollutants and Its Adsorption Mechanisms

Emerging pollutants (EPs) are a group of toxins with low concentrations but substantial toxicity. In recent years, the environment has gained a lot of attention. These trace contaminants can accumulate in different sources and eventually make their way into human bodies, creating a public health risk. Biochar adsorbents are being applied to treat wastewater for removal of emerging contaminants (ECs) as a low-cost and effective adsorbent. However, biochar adsorbents needs improvement for the treat of emulsifiable concentrated water. Several attempts have been made to confiscate ECs from effluents by modified biochar (mBC) which are currently available. Various techniques of functionalizing biochar with different physicochemical properties have been investigated, resulting in different impacts, behaviors, and adsorption processes of customized biochar on various EPs. It is vital to evaluate and assimilate information regarding EC adsorption systematically. Concerning modified biochar, the first method for removing ECs from charcoal is discussed in this paper. The performance and adsorption mechanism of mBC on conventional EPs is examined. Furthermore, the leading trends, developments, ideas and recommendations for impending progress, are discussed.

Automated summary

Emerging pollutants (EPs) are toxins with low concentrations but substantial toxicity that have gained attention due to environmental concerns. These trace contaminants can accumulate in various sources and pose a public health risk when they make their way into human bodies. Biochar adsorbents have been used as low-cost and effective means for treating wastewater and removing EPs. However, improvements are needed for the treatment of emulsifiable concentrated water using biochar adsorbents. Modified biochar (mBC) techniques have been investigated to confiscate EPs from effluents, resulting in different impacts and adsorption processes. Therefore, it is important to systematically evaluate and assimilate information regarding the adsorption of EPs by modified biochar.
