1：Experimental Design and Method Selection:

The study used a hybrid Ag-TiO2/DM photocatalyst synthesized by the sol-gel method, with photocatalytic reactions performed in a semi-batch reactor under solar lamp illumination. Endpoints included chlorophyll a, photosynthetic efficiency, and flow cytometry measurements.

2：Sample Selection and Data Sources:

Axenic cultures of Microcystis aeruginosa and Oscillatoria tenuisa cyanobacteria were obtained from Renyi-Tan Reservoir, Taiwan, and grown in standard media.

3：List of Experimental Equipment and Materials:

Equipment included a solar lamp (Suntest AM1, Hanau, Germany), flow cytometer (FACScan, D-48161 Partec, Münster, Germany), liquid scintillation counter (B2810TR, PerkinElmer), ICP-OES (model 2100DV, Perkin-Elmer), GC/MS (model GC-6890N, MS-5973N, Agilent), and GC/ECD (HP 6890N, Agilent). Materials included titanium isopropoxide, isopropyl alcohol, silver nitrate, diatomite, propidium iodide, SYBR green I, and various chemicals for media and analysis.

4：Experimental Procedures and Operational Workflow:

Photocatalytic reactions were conducted with varying Ag-TiO2/DM dosages (520-2100 mg/L) for up to 24 h under light. Samples were collected at intervals for analysis of chlorophyll a, photosynthetic activity (using carbon-14 method), flow cytometry, DOC, potassium ions, DBP formation, and mutagenicity tests.

5：Data Analysis Methods:

Data were analyzed using statistical methods for dose-response relationships, with specific techniques like spectrophotometry for chlorophyll a, flow cytometry for cell viability, and standard methods for DBP and mutagenicity analysis.
