In this study, Ru(III) ions were utilized to activate periodate (PI) for oxidation of trace organic pollutants (TOPs, e.g., carbamazepine (CBZ)). The Ru(III)/PI system can significantly promote the CBZ in a wide initial pH range (3.0–11.0) at 1 μM Ru(III), showing much higher performance than transition metal (i.e., Fe(II), Co(II), Zn(II), Fe(III), Cu(II), Ni(II), Mn(II), and Ce(III)) noble ion Ag(I), Pd(II), Pt(II), Ir(III)) activated PI systems. Probe experiments, UV–vis spectra, X-ray absorption near-edge structure (XANES) spectra confirmed high-valent Ru-oxo species (Ru(V)=O) as dominant oxidant process. Because role Ru(V)=O, process exhibited remarkable selectivity strong anti-interference TOPs complex water matrices. Ru(V)=O undertake 1-e– 2-e– transfer reactions via catalytic cycles → Ru(IV) respectively. utilization efficiency approach 100% under optimal conditions. stoichiometrically transformed into IO3– without production undesired iodine (e.g., HOI I2). This study developed an efficient environmentally benign advanced rapid removal enriched understandings on reactivity Ru cycles.
