Embodiment 1

[0041] a kind of Fe 78 Si 11 B 11 A method for preparing an amorphous alloy strip, comprising the steps of:

[0042] 1) The composition of the amorphous alloy strip is Fe 78 Si 11 B 11 , is a component with strong amorphous forming ability; converted to the required mass of each element by atomic percentage, weighed Fe, Si, B, and placed Fe, Si, B in the water-cooled crucible of the melting furnace. Before smelting, vacuumize the smelting furnace (vacuum degree is 5×10 -3 Pa), and then began to clean the smelting furnace, filled with high-purity argon during the cleaning process, and then vacuumed again after each cleaning, cleaning 4 times. The arc melting of alloy raw materials is carried out under the protection of high-purity argon. Before smelting the alloy raw materials, it is necessary to arc-melt the sponge titanium ingot in the crucible. The purpose of this is to absorb the excess oxygen in the furnace cavity and prevent the sample from being oxidized during the ...

Abstract

The invention belongs to the technical field of wastewater treatment, and discloses an Fe-Si-B amorphous alloy strip, a preparation method thereof and application of the Fe-Si-B amorphous alloy stripin degradation of azo dye wastewater. The composition of the Fe-Si-B amorphous alloy strip is FemSinBp, wherein m is larger than or equal to 75 and smaller than or equal to 83, n is larger than or equal to 7 and smaller than or equal to 15, p is larger than or equal to 7 and smaller than or equal to 15, and m+n+p is equal to 100; and preferably, the composition of the Fe-Si-B amorphous alloy stripis Fe78Si11B11. The invention further discloses a preparation method of the Fe-Si-B amorphous alloy strip and application of the Fe-Si-B amorphous alloy strip in degradation of the azo dye wastewater. The strip provided by the invention has relatively good corrosion resistance and relatively high catalytic activity, has very fast degradation rate to azo dyes and is low in cost.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and relates to Fe-based amorphous alloy materials and their application in dye wastewater treatment, in particular to a Fe-Si-B amorphous alloy strip and its preparation and degradation in azo dye wastewater in the application. Background technique [0002] Water is the source of life and supports all life. It is not only a basic resource but also a strategic resource. With the growth of population and the development of social economy, people's demand for water continues to increase. The shortage of water resources and the pollution of the water environment are becoming more and more prominent, seriously disturbing the survival and development of human beings. Sewage treatment is no longer limited to a certain region, but has extended to the entire society, becoming a global and cross-century problem. Among them, dye wastewater, as a high-concentration organic wastewater, has the ...
