Embodiment Construction

[0039] The specific implementation of the present invention will be further described below in combination with examples and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0040] An iron-based (Fe 76 Si 13 B 9 m 2 and Fe 78 Si 11 B 9 m 2 (M=P, Y, V, Sn and Zr)) A method for preparing an amorphous alloy strip, comprising the following steps:

[0041] 1) Ingredients

[0042] Prepare the required alloy according to the atomic percentage converted into the required mass of each element. The purity of the raw materials used is ≥99.5wt.%. Before the alloy is prepared, first remove the oxide layer on the metal surface, then clean it with alcohol, and dry it for later use; The precision balance weighs the mass of the required alloy components, and the error is controlled within ±1%.

[0043] 2) Master alloy melting

[0044] The alloy is smelted in a vacuum non-consumable electric arc furnace, and the electrodes used in the elec...

Abstract

The invention discloses an iron-based series amorphous alloy strip and a preparation method thereof and application in degradation of azo dye wastewater, and belongs to the technical field of azo dye-containing wastewater treatment. The iron-based series amorphous alloy strip is Fe(78-x)Si13B9Mx or Fe78Si(13-x)B9Mx, wherein M is Zr or Sn or P or V or Y, and x is larger than 0 and smaller than or equal to 3. The iron-based series amorphous strip has better corrosion resistance, higher catalytic activity, higher degradation efficiency and rate for azo dyes, and shows good comprehensive performance.

Description

technical field [0001] The invention belongs to the technical field of degradation treatment of azo dye-containing wastewater, and relates to a series of iron-based amorphous alloy materials and their application in the treatment of azo-dye-containing wastewater, in particular to an iron-based series amorphous alloy strip and its Preparation method and application in degrading azo dye wastewater. Background technique [0002] Water is the source of life. As we all know, about 71% of the earth's surface is covered by water, of which salt water accounts for 97.5%, and the usable fresh water resources only account for 2.5% of water resources. Among them, the water that is really usable by humans The resource is only 0.007%, which is very little. Therefore, there are still many people in the world who are suffering from water shortage. In recent years, with the development of my country's economy, especially the rapid development of heavy industry and light industry, water pol...
