Abstract

The invention discloses a degradation method of acid orange II dye wastewater. The method comprises the following steps: putting an Mg78Zn22 semi-amorphous strip into a citric acid solution for pretreatment, and then putting the pretreated Mg78Zn22 semi-amorphous strip into the acid orange II wastewater to degrade acid orange II. After pretreatment of the Mg78Zn22 semi-amorphous strip in the citric acid solution; a developed honeycomb network structure is formed on the surface of the semi-amorphous strip, so the microscopic surface area of the Mg78Zn22 semi-amorphous strip is increased, and more active sites enabling semi-amorphous strip atoms and acid orange II molecules to react with each other are provided; and therefore, a degradation rate is increased.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a degradation method for acid orange II dye wastewater. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Semi-amorphous alloy is a new material between amorphous alloy and crystal alloy. Semi-amorphous alloys not only have the characteristics of short-range order and long-range disorder of atomic arrangement in amorphous alloys, but also have the characteristics of long-range order in the arrangement of atoms in crystalline alloys. Therefore, the structural chemical composition of the semi-amorphous alloy is relatively uniform, and there will be a cert...
