Heterogeneous Catalytic Degradation of Diuron Using Algerian Sodium Montmorillonite

Diuron is categorized as a probable human carcinogen by the United States Environmental Protection Agency (EPA). This work aimed to determine optimal conditions for catalytic degradation of in an aqueous solution with H2O2 using Algerian sodium Montmorillonite (Mont-Na) catalyst. The material characterized before and after experiment X-ray diffraction, Fourier transform infrared (FTIR) spectroscopy, specific surface area (SBET), elemental analysis, thermal analysis (TGA/DTA). charge determined measuring point zero charge. Tests without Mont-Na provide 32% conversion rate 8 h. However, mixture 1 g increases 91% 180 min at 25 °C pH 6.3. disappearance evidenced high-performance liquid chromatography UV–vis detector (HPLC/UV–vis). Specifically, 3,4-dichloroaniline (DCA) only by-product. At basic values 9 11, 72.5% achieved lower contact time 150 min. A change temperature toward higher results decrease rate. Overall, used successfully heterogeneous from polluted water.
