- Аннотация: Currently, a serious threat for living organisms and human life in particular, is watercontamination with persistent organic and inorganic pollutants. To date, several techniques havebeen adopted to remove/treat organics and toxic contaminants. Adsorption is one of the mosteffective and economical methods for this purpose. Generally, porous materials are considered asappropriate adsorbents for water purification. Conventional adsorbents such as activated carbonshave a limited possibility of surface modification (texture and functionality), and their adsorptioncapacity is difficult to control. Therefore, despite the significant progress achieved in the developmentof the systems for water remediation, there is still a need for novel adsorptive materials withtunable functional characteristics. This review addresses the new trends in the development of newadsorbent materials. Herein, modern carbon-based materials, such as graphene, oxidized carbon,carbon nanotubes, biomass-derived carbonaceous matrices—biochars as well as their compositeswith metal-organic frameworks (MOFs) and MOF-derived highly-ordered carbons are consideredas advanced adsorbents for removal of hazardous organics from drinking water, process water,and leachate. The review is focused on the preparation and modification of these next-generationcarbon-based adsorbents and analysis of their adsorption performance including possible adsorptionmechanisms. Simultaneously, some weak points of modern carbon-based adsorbents are analyzedas well as the routes to conquer them. For instance, for removal of large quantities of pollutants,the combination of adsorption and other methods, like sedimentation may be recommended. Anumber of efficient strategies for further enhancing the adsorption performance of the carbon-basedadsorbents, in particular, integrating approaches and further rational functionalization, includingcomposing these adsorbents (of two or even three types) can be recommended. The cost reductionand efficient regeneration must also be in the focus of future research endeavors. The targetedoptimization of the discussed carbon-based adsorbents associated with detailed studies of theadsorption process, especially, for multicomponent adsorbate solution, will pave a bright avenue forefficient water remediation.
