Preparation of Soybean Dreg-Based Biochar@TiO₂ Composites and the Photocatalytic Degradation of Aflatoxin B₁ Exposed to Simulated Sunlight Irradiation.

ABSTRACT: Aflatoxin B₁ (AFB₁) is a highly toxic carcinogen severely harmful to humans and animals. This study fabricated SDB-6-K-9@TiO₂ composites via the hydrothermal synthesis method to reduce AFB₁. The structural characterization results of the photocatalytic composites showed that TiO₂ was successfully loaded onto SDB-6-K-9. The different photocatalytic degradation conditions, photocatalyst kinetics, recycling performance, and photocatalytic degradation mechanism were investigated. Photocatalysis with 6 mg of 4%SDB-6-K-9@TiO₂ in a 100 μg/mL AFB₁ solution presented a reduction of over 95%, exhibiting excellent performance, high stability, and reusability even after five cycles of photocatalytic experiments.
