The mineralization ability of a chloride-resistant γ-Cu₂(OH)₃Cl Fenton catalyst: effects of the cation type, salt concentration and organic pollutants

Abstract

A chloride-resistant heterogeneous Fenton catalyst γ-Cu2(OH)3Cl is used to mineralize aromatic organics (phenol, bisphenol A, salicylic acid and aniline) in saline solutions with different salts (MgCl2, CaCl2, NaCl and KCl) and concentrations.

Synthesis of γ-Cu2(OH)3Cl/LDH composites as Fenton catalysts to mineralize aniline: successive mineralization by hydroxyl and superoxide radicals

“…The latest research indicated g-Cu 2 (OH) 3 Cl possessed a superior chloride-resistant ability to effectively mineralize organics in high chloride solutions. 13,14 LDHs can couple with other metal-based or carbonaceous materials to form novel composites, which is a good alternative to enhance their catalytic performance in Fenton reactions. 5 Cubased LDHs and g-Cu 2 (OH) 3 Cl have similar layered structures and contain Cu-OH octahedra.…”
