Tóm tắt

Landfill leachate nanofiltration concentrates (LLNC) contain complex organic pollutants that are difficult to treat. This study developed a copper-doped attapulgite-chitosan composite catalyst (Cu@ATP-CTS) for efficient LLNC degradation in a Fenton-like system. The incorporation of attapulgite extended the effective pH range of Fenton reactions from 2 to 8, overcoming traditional limitations. Optimized via response surface methodology, the catalyst achieved 89.02% UV
