Biochar for Water Pollution Control: From Sensing to Decontamination

Biochar, a biologically originated carbon-rich material derived from the oxygen-limited pyrolysis of biomass, is usually added to soil for its enrichment, increasing water-holding capacity and pH. This revolutionary thus contributes reduction in overall environmental impact mitigation climate change. Due beneficial properties this material, especially electrochemical applications (large active surface area, conductivity, etc.), biochar demonstrates an extremely high adsorption detection micropollutants simultaneously. However, finding optimal conditions adsorptive prepared biochar-based sensors crucial. The efficiency should be sufficient remove pollutants, even complex matrices; on other hand, properties, such as conductivity charge transfer resistance, are key factors concerning sensing ability. Therefore, balanced design can ensure both usability effectiveness sensing. To enhance levels electroactivity that already high, pre- or post-modification performed. Such recycled carbon-based materials could promising candidates among platforms. In study, different modifications presented. Utilizing important it possible create bifunctional platform removing water systems simultaneously confirming purification via their detection. We reviewed use effective removal methods matrices.
