1：Experimental Design and Method Selection:

The study evaluates the photocatalytic degradation of AFB1 using AC/TiO2 catalyst under UV-Vis light, employing hydrothermal synthesis for catalyst preparation and various analytical techniques for characterization and degradation assessment.

2：Sample Selection and Data Sources:

AFB1 standard was purchased from Sigma-Aldrich and diluted with methanol. Activated carbon (AC) was purchased from Heng Sheng Huan bao Co. Ltd, and TiO2 nanopowder (P25) was commercially obtained.

3：List of Experimental Equipment and Materials:

Equipment includes SEM (Quanta 250 FEG, FEI company), XRD (Bruker D8-advance), FT-IR spectrometer (Bruker ALPHA), UV-Vis spectrophotometer (UV-3000, Mapada Instruments), high-pressure mercury lamp (130W, 350-450nm wavelengths), HPLC (Agilent 1290) with XDB C18 column. Materials include AFB1, AC, TiO2, butyl titanate, methanol, acetonitrile, HNO3, and various chemicals and solvents.

4：Experimental Procedures and Operational Workflow:

AC/TiO2 was prepared via hydrothermal synthesis at 180°C for 12h. Photocatalytic degradation involved stirring AFB1 solution with catalyst in dark for 30min, irradiating with light, sampling at intervals, centrifuging, and analyzing AFB1 concentration by HPLC. Factors like catalyst dosage, pH, light source, and AFB1 concentration were varied.

5：2h. Photocatalytic degradation involved stirring AFB1 solution with catalyst in dark for 30min, irradiating with light, sampling at intervals, centrifuging, and analyzing AFB1 concentration by HPLC. Factors like catalyst dosage, pH, light source, and AFB1 concentration were varied. Data Analysis Methods:

5. Data Analysis Methods: Degradation rate was calculated using Dr = (C0-Ct)/C0 × 100. Kinetics were analyzed using pseudo-first-order model ln(C0/C) = Kt. Statistical analysis included fitting data to models and comparing efficiencies.
