Concluding Remarks A extensive study primarily based on numerous modification procedures on AC derived from biomass to raise its adsorption capability was presented. Many techniques have been established to develop a brand new generation of various surface functional groups in ACs, which includes acid therapy, base treatment, salt treatment, ozone therapy, impregnation treatment, plasma therapy, and microwave treatment. The experimental final results indicate that the acidic remedy demands uptake of metal ions though base treatment is applied mostly for the removal of anionic and organic compounds from an aqueous environment. Findings on ACs with surfactant amendments, which are developed to remove contaminants from aqueous solutions, are limited and as a GNF6702 References result demand more exploration to impart superb overall performance. The plasma method for producing an appropriate charge on superficial carbon is definitely an effective strategy to create the desired charge around the AC surface generating it useful for the elimination of toxic pollutants. Additionally, carbon-based materials with basic surfaces to incorporate CO2 adsorption in order to attenuate global warming are exceptionally desirable. On the other hand, further investigation is necessary of the surfactant modification of ACs that can be tailored to get rid of pollutants from an aqueous environment to yield superb performance as experimental findings in this field are limited. To choose a modifying agent, some variables like the charge (positive, unfavorable, or neutral), state (solid, liquid, gaseous), size, solubility, and pH of the method are necessary. Nevertheless, some of the important drawbacks of modification solutions contain the connected charges involved within the approach as well as the leaching of hazardous chemical compounds employed in the alternation method into the treated water. Considering the effects of increased/decreased smell of certain contaminants, selective adsorption could be generated, and also the reclamation with the adsorbents needs to be utilized in cyclic measurements and quietly. Taking into consideration the above, the location demands novel, sustainable, and environmentally friendly approaches for activated carbon modification. Hence, the authors recommend that existing modification procedures ought to be enhanced as these approaches boost the chemical surfaces of ACsNanomaterials 2021, 11,15 ofwhile limiting the degradation of textural functions. It would also market the dominance on the AC adsorption process of water/wastewater therapy along with other applications.Author Contributions: Conceptualization, M.K.J. and H.R.P.; methodology, M.K.J., S.J. and R.K.S.; application, M.K.J. and a.A.K.; validation, H.R.P. and M.P.; formal evaluation, B.P. and H.R.P.; investigation, H.R.P.; sources, H.R.P. and M.P.; data curation, M.K.J., R.K.S. and S.J.; writing–original draft preparation, M.K.J., B.P., A.A.K. and H.R.P.; writing–review and editing, M.K.J., B.P. and H.R.P.; visualization, H.R.P. and M.P.; LY294002 In stock supervision, B.P., M.P. and H.R.P.; project administration, H.R.P. and M.P.; funding acquisition, H.R.P. and M.P.
