摘要
黏土因一系列优异性能而被广泛应用于黏土基吸附剂及催化剂的制备,并用于废水中难降解有机物的降解研究。系统总结了黏土基非均相催化剂的制备方法,阐述了黏土基非均相催化剂在难降解废水处理领域的研究现状。其中黏土基非均相催化剂的分离、催化剂形貌的控制、活性组分的浸出问题、难降解有机物降解过程动力学及机理等方面的问题仍然是今后研究的重点。
Clay has been widely used in the preparation of clay supported adsorbents and catalysts due to a serious of excellent properties.Those clay products have been widely applied to the degradation of refractory organic wastewater.The preparation methods of heterogeneous catalysts based on clay were systematically summarized,and the research status of refractory wastewater degradation based clay heterogeneous catalysts was introduced.The separation of heterogeneous clay-catalysts,control of the morphology,leaching of the active components,kinetics and mechanism of degradation of refractory organic wastewater were still the focus of future research.
