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.
