摘要：

[GRAPHICS] Cyanuric acid is unique among organic molecules in being resistant to photocatalytic degradative conditions by TiO2 in oxygenated water. Trimethyl cyanurate shows an isotope effect of 3.1-3.3 on degradation selectivity when the methyl groups are deuterated, and cyanuric acid enriched in O-18 does not exchange hydroxyl groups with bulk water under these conditions. Thus, the tolerance of cyanuric acid to photocatalysis is not due to rapid and reversible addition to the aromatic nucleus.
