摘要：
An investigate was carried out to evaluate the catalytic performance of a Fe, Al-pillared bentonite for heterogeneous photo-Fenton systems. The catalyst was prepared by a cation doping technique and X-ray diffiraction and infraed spectroscopy were used to characterize its properties. The results showed that the main format of Fe was amorphous FeOOH. Some bands of infrared spectroscopy shifted to lower wave length, indicating Fe and Al has intercalated into the layers of the bentonite. The Fe, Al-pillared bentonite exhibited a high catalytic activity under neutral condition. Complete discoloration was achieved in less than 60min and mineralization ratio reached 76.9% in 120min. The catalytic activity decreased as the pH increased and the initial concentration of Orange II increased.
