Abstract With social progress and industrial development, heavy metal pollution in water soils environment is becoming more serious. Although biochar a low-cost environmentally friendly adsorbent for ions, its adsorption immobilization efficiency still need to be improved. As an upgraded version of biochar, modified has attracted extensive attention the scientific community. This review summarized recent research on treatment methods pollutants using biochar. The features advantages modification techniques such as physical modification, chemical biological other categories were discussed. mechanism removing metals from soil by was summarized. It found that had better performance after which provided higher surface areas functional groups, enough binding sites combine ions. Biochar very promising candidate environment. Furthermore, some high valent ions could reduced low metals, Cr(VI) reduction Cr(III), form precipitates in-situ sorption-reduction-precipitation strategy. However, it direction efforts develop high-efficiency with low-cost, sorption capacity, photocatalytic performance, no secondary future.

Recent trends and economic significance of modified/functionalized biochars for remediation of environmental pollutants

Scientific Reports, Год журнала: 2024, Номер 14(1)

Опубликована: Янв. 2, 2024

The pollution of soil and aquatic systems by inorganic organic chemicals has become a global concern. Economical, eco-friendly, sustainable solutions are direly required to alleviate the deleterious effects these ensure human well-being environmental sustainability. In recent decades, biochar emerged as an efficient material encompassing huge potential decontaminate wide range pollutants from systems. However, application raw biochars for pollutant remediation is confronting major challenge not getting desired decontamination results due its specific properties. Thus, multiple functionalizing/modification techniques have been introduced alter physicochemical molecular attributes increase their efficacy in remediation. This review provides comprehensive overview latest advancements developing functionalized/modified via biological other physiochemical techniques. Related mechanisms further applications modified water discussed summarized. Furthermore, existing research gaps challenges discussed, well study needs suggested. work epitomizes scientific prospects complete understanding employing candidate polluted regenerative development.
