摘要:

采用MIL-88(Fe)金属有机骨架材料湿法高效催化降解染料废水中罗丹明B。通过FT-IR、XRD和TEM等对MIL-88(Fe)金属有机骨架材料进行了表征,并考察了MIL-88(Fe)金属有机骨架材料催化降解罗丹明B的效果和催化机理。结果表明,在优化条件下,MIL-88(Fe)-H2O2反应体系对100 mg/L罗丹明B的去除率可达99.3%。MIL-88(Fe)金属有机骨架材料有望成为一种高效降解染料废水中有机污染物的类Fenton催化剂。

Abstract:

MIL-88(Fe) metal organic frameworks has been used for the high-efficiency catalytic degradation of Rhodamine B(RhB) in dye wastewater by wet method, and characterized by means of FT-IR, XRD, TEM, etc. The effects of MIL-88(Fe) metal organic frameworks on the catalytic degradation of RhB, and its catalytic mechanisms have been investigated. The results show that under optimized conditions, the removing rate of 100 mg/L of RhB by MIL-88(Fe)-H2O2 reaction system can reach 99.3%. MIL-88(Fe) metal organic frameworks is expected to become a kind of Fenton-like catalyst for the high-efficiency degradation of organic pollutants in dye wastewater.

Key words: MIL-88(Fe) metal organic frameworks, Rhodamine B, dye wastewater
