Biochar (pyrolyzed organic material) has been increasingly recognized for its catalytic role in facilitating the advanced oxidation of emerging pollutants. However, inherent capacity remains highly uncontrollable, leading to considerable uncertainty when scaling up real-world applications. This study explores intensified biochar coated with CaO2 generating hydroxyl radicals (OH·) and tebuconazole, a prevalent fungicide, tebuconazole was selected as representative pesticide agricultural drainage. In addition evaluating potential degradation by processes (AOPs), adsorption capabilities two commercially available biochars, one derived from waste (ABC) other spruce chips (SBC), well their CaO2-coated derivatives (ABC/CaO2 SBC/CaO2), were also assessed. By taking advantage strong biochar, activating AOPs at sites CaO2, this material enables more efficient targeted removal tebuconazole. The results indicate that coating on promoted over tenfold increase generation OH·, resulting 99% within 10 min. Despite decrease 40–50% resulted coating, 10-minutes overall performance significantly enhanced. is closely related surface chemical properties, particularly presence persistent free which can be regenerated. research paves new way employing CaO2-enhanced mitigation measures.

In agricultural production, pesticides play an important role in increasing crop yields. However, pesticide residues are caused by improper handling users during the production process. Chlorine dioxide and ozone, as strong oxidants with similarity spatial structure, effectively degrade widely used water treatment food industry. order to better understand mechanism of chlorine ozone on pesticides, properties introduced this review. Herbicides, insecticides, fungicides were selected for study, influencing factors, kinetics, degradation pathways degraded presented. The follows second-order kinetic model, reacting functional groups high electron density transfer. Ozone selectively undergoes electrophilic reactions solution. addition, when reaction system is alkaline, accelerates decomposition form hydroxyl radicals (·OH), which react pesticides. satisfies pseudo-first-order model. By comparing paper provides a theoretical basis solving problem industry future.
