摘要：

4-nitrophenol is degraded by H2O2 with iron (III)-exchanged and pillared montmorillonite as catalysts. The influence of different types of catalysts, their amounts and the H2O2 concentration were investigated. At optimal conditions, a solution containing 10(-3) M of 4-nitrophenol and 10(-2) M of H2O2 was degraded in less than 6 h in the presence of (1 g/1) of mixed (Al-Fe) pillared montmorillonite (prepared by pillaring montmorillonite with mixed Al and Fe oxides).
