Engineered biochar for environmental decontamination in aquatic and soil systems: a review

Carbon Research, Journal Year: 2022, Volume and Issue: 1(1)

Published: June 18, 2022

Abstract Contamination of aquatic and soil systems by organic inorganic pollutants has become a serious issue concern worldwide. Viable cost-effective solutions are urgently needed to mitigate the negative impacts diverse on environment human health. Biochar emerged as an effective green material for remediation wide spectrum (in)organic pollutants. However, applications pristine biochar in decontamination have encountered bottlenecks due its limited properties which cannot meet desired requirements. Therefore, multiple modification methods been developed tailoring physicochemical enhance effectiveness environmental decontamination. This work provides holistic review recent advances synthesis engineered using physical, chemical, biological methods. Further related mechanisms field also summarized discussed. In addition, existing challenges research gaps outlined, future needs proposed. summarizes scientific opportunities comprehensive understanding biochars materials contaminated water soil.

Biochar as a Green Sorbent for Remediation of Polluted Soils and Associated Toxicity Risks: A Critical Review

Separations, Journal Year: 2023, Volume and Issue: 10(3), P. 197 - 197

Published: March 13, 2023

Soil contamination with organic contaminants and various heavy metals has become a global environmental concern. Biochar application for the remediation of polluted soils may render novel solution to soil issues. However, complexity decontaminating mechanisms real environment significantly influences preparation large-scale biochar ramification. This review paper highlights utilization in immobilizing eliminating pollutants from contaminated factors affecting efficacy biochar. Furthermore, risks related unpolluted agricultural are also debated. production conditions (pyrolysis temperature, feedstock type, residence time) rate greatly influence performance remediating soils. Biochars prepared at high temperatures (800 °C) contained more porosity specific surface area, thus offering adsorption potential. The redox electrostatic contributed oxyanions, whereas ion exchange, complexation, precipitation were mainly involved cations. Volatile compounds (VOCs), dioxins, polycyclic aromatic hydrocarbons (PAHs) produced during pyrolysis induce negative impacts on alga, microbes, plants. A careful selection its compatibility carbonization technology having suitable operating is essential avoid these impurities. It would help prepare desired features target particular pollutant site. provided explicit knowledge developing cost-effective, environment-friendly biochar, which could be used decontaminate targeted large scale. future study directions described ensure sustainable safe as improver reclamation

Modified Biochars and Their Effects on Soil Quality: A Review

Environments, Journal Year: 2022, Volume and Issue: 9(5), P. 60 - 60

Published: May 15, 2022

Biochar (BC) has attracted attention due to its impacts on soil quality by enhancing fertility, carbon storage and contaminants immobilization. BC also induces changes in microbial community structure enhances crop productivity long term scenarios compared many other organic amendments. However, information related the role of modified BCs altering is still scarce. can be using physical, chemical methods. Modified change functional groups, pore size, structure, surface area properties soil, which plays a key changing quality. The addition as amendment increased CEC (cation exchange capacity), EC (electron conductivity), pH, matter, hydraulic conductivity, porosity, infiltration rate, activities (enzymes community), nutrient profile gas properties, but it varies according pervading environmental conditions. This study provides basis for effective practical approaches modifying improving
