Organometallic framework (MOFs) is a kind of controlled pore, high specific surface area, pore structure rules, functional and other porous polymers, since the organic by a single metal atom (or metal clusters) and multi-ligand group ligands, structure rules, rigid porous network. In the catalyst, pesticides, pharmaceuticals and other industries use more widely. With the rapid development of photocatalytic materials, a number of MOFs have semiconducting get attention in the field of catalysis light, In this paper, MOFs have these characteristics, using its heterogeneous reaction with H2O2, produce hydroxyl radicals, Rhodamine B color degradation process wastewater.In this paper, experimental study combining practical, use of the laboratory-made catalyst Fe-MIL-101and H2O2heterogeneous Fenton reaction occurs degradation of rhodamine B dye solution. And in order to investigate the optimal reaction conditions. Experimental results show that the catalyst Fe-MIL-101in an amount of0.8g/L, the amount of H2O220mmol/L, the temperature is room temperature, the reaction solution pH=3-4, the optimum reaction conditions. At this time the reaction40min degradation rate of80%or more at normal temperature and pressure.This paper reflects on the basis of the above and discussed in this laboratory-made Fe-MIL-53Fe/MIL-125(Ti)(iron modified MOFs) and H2O2heterogeneous Fenton reaction occurs degradation of rhodamine B dye solution and. Also we discuss the optimal reaction conditions for their reactions.In this paper Fe-MIL-101, Fe-MIL-53and Fe/MIL-125(Ti) catalyst heterogeneous Fenton reaction, the material synthesized SEM, N2adsorption desorption, XRD, and further investigate the adsorption and catalytic properties of the series material. And the above-mentioned material for heterogeneous Fenton reaction H2O2degradation of rhodamine B, and in light catalytic conditions, the reaction is more rapid,30min conversion rate of more than90%of rhodamine B degradation and bleaching tests showed these materials have good value heterogeneous Fenton reaction. |
