Webb14 apr. 2024 · A total of 1.00 g of AHA was dissolved in 100 mL of phosphate-buffered saline (PBS, pH = 5.0) followed by adding DA of equal molar (AHA/DA = 1:1) and stirring for 10 h with the protection of nitrogen and under dark conditions at room temperature. The specific preparation scheme is shown in Table S3. Webb14 mars 2024 · In addition, the changes in pollutant types (CT and RE) had little effect on pH, indicating that the pH environment of CT and RE were consistent during the reaction. Since the PH of the reaction system was in the weakly acidic to neutral range, the photocatalytic degradation experiments were performed at initial pHs of 4.5, 5.5, and 6.5 …
