Catalytic wet peroxide oxidation degradation of magenta wastewater and preparation of FeOCl/montmorillonite

The iron oxychloride/pillared montmorillonite (FeOCl/MMT) catalyst was prepared by wet impregnation method and solid melting method. Various characterization techniques were used to analyze the microscopic morphology and structure of a series of catalysts. Moreover, the catalysts were used to treat...
