Problems solved by technology

Because there are many types of dust and mud, and the content of various elements varies greatly, there is currently no national standard method to detect various elements in it.
In addition, the composition of dust and mud samples is complex, and the existing detection method for zinc element is mainly chemical titration method. The percentage content of zinc element is obtained. The procedure of wet detection of zinc element in dust and mud is cumbersome and time-consuming. There are many kinds of pharmaceutical reagents added, which have a certain impact on the environment.

Embodiment Construction

[0013] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail in conjunction with the following examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0014] The invention provides a method for detecting zinc in dust by using atomic absorption spectrum. Dust sludge is caused by the tumbling of molten steel and the bursting of airflow on the surface of the melt during the oxygen-blowing smelting process of the converter, which evaporates a certain amount of iron and iron oxides and escapes with the furnace gas. air into the flue. The flue gas is wetted with water, captured and concentrated to become converter dust. The converter dust sludge contains zinc element. The specific steps of the method for detecting zinc in the dust sludge by using atomic absorption spectro...

Abstract

The invention belongs to the technical field of chemical element detection, and provides a method for detecting zinc in dust mud based on atomic absorption spectrometry, which is less in detection interference, high in accuracy, low in detection limit, high in detection speed, capable of detecting samples with higher content through a dilution method, and suitable for detecting samples with complex dust mud components. The method can simplify the detection means of the zinc element in the dust mud, reduces reagents used for detection, improves the efficiency, and is a simple and efficient detection method.

Description

technical field [0001] The invention belongs to the technical field of chemical element detection and provides a method for detecting zinc in dust and mud based on atomic absorption spectroscopy. Background technique [0002] The high-speed converter steelmaking process will produce a large amount of dust and sludge, which contains a large amount of iron, carbon, calcium, zinc and other elements, and has high recycling value. Before recycling, it is necessary to first determine the content of various elements in the dust sludge, and provide reliable data support for the recycling and reuse of dust sludge, so as to maximize the use of this resource. Because there are many types of dust and mud, and the contents of various elements vary greatly, there is currently no national standard method to detect various elements in it. In addition, the composition of dust and mud samples is complex, and the existing detection method for zinc element is mainly chemical titration method. ...
