In terms of cerium, the results were notably low, with "2 B 1 CE 0.06 AG" showing a leaching concentration of only 0.04 PPM, and the "2 B 0.1 CE 0.06 AG" sample demonstrating no detectable leaching (0.00 PPM). This suggests that cerium is highly stable in both formulations, making it a reliable component in photocatalytic applications. Titanium leaching was also assessed, with "2 B 1 CE 0.06 AG" showing 0.24 PPM and "2 B 0.1 CE 0.06 AG" at 0.11 PPM. These results indicate a moderate level of titanium leaching, which may warrant further investigation to enhance the photocatalyst's longevity.
