Abstract

The invention provides a method for analyzing and detecting sodium content and potassium content in a covering agent. The method comprises the following steps: preparing sodium chloride standard solution with different mass concentrations, carrying out spectrum analysis on the sodium chloride standard solution by a plasma emission spectrometer to obtain corresponding emission intensity, and creating a standard curve of sodium according to the mass concentration and the emission intensity; preparing potassium chloride standard solution with different mass concentrations, carrying out spectrum analysis on the potassium chloride standard solution by the plasma emission spectrometer to obtain corresponding emission intensity, and creating a standard curve of potassium according to the mass concentration and the emission strength; and carrying out spectrum analysis on a covering agent sample to be detected by the plasma emission spectrometer to obtain the emission intensity of sodium and the emission intensity of potassium, obtaining the sodium content according to the standard curve of sodium and the emission intensity of sodium, and obtaining the potassium content according to the standard curve of potassium and the emission intensity of potassium.

Description

technical field [0001] The invention belongs to the technical field of analysis methods, and in particular relates to an analysis and detection method for sodium content and potassium content in a covering agent. Background technique [0002] Aluminum alloy is the most widely used type of non-ferrous metal structure in the industry, and has been widely used in aerospace, aviation, automobile, machinery manufacturing, shipbuilding and chemical industries. The preparation process of aluminum alloy generally includes the following steps: smelting and casting each alloy element, and then performing different post-treatments according to different uses, such as annealing and homogenization. [0003] Aluminum is a relatively active metal. During the smelting process of aluminum alloy, aluminum is easily oxidized to form oxides; during the smelting process, the melt will also absorb part of the gas. After these oxides or gases enter the ingot with the melt, Slag inclusions, oxide ...
