Abstract:
... It has been documented that organic contaminants can be degraded by hydroxyl radicals (•OH) produced by the activation of H₂O₂ by Fe(II)-bearing clay. However, the interfacial electron transfer reactions between structural Fe(II) and H₂O₂ for •OH generation and its effects on contaminant remediation are unclear. In this study, we first investigated the relation between •OH generation sites and sul ...

Hexavalent chromium (Cr(VI)) was activated by ultraviolet-A light-emitting diode (UVA-LED), resulting in efficient removal of various pollutants, including dye, pharmaceuticals, and pesticides, with pseudo-first-order rate constants of 0.0610–0.159 min⁻¹. Comparatively, UVA-LED or Cr(VI) alone barely degraded selected pollutants. Both HO• and Cr(V) were produced in the UVA-LED/Cr(VI) system based ...
