Abstract

The invention discloses a method for detecting the contents of strontium, iron, barium, magnesium and calcium in a zinc-strontium alloy, which comprises: heating and dissolving the zinc-strontium alloy in a solvent, and diluting to obtain an analysis solution, the mass concentration of which is 0.01 ±0.005%, the solvent contains 0.1-0.3% sodium rosinate soap; select the analysis line of strontium, iron, barium, magnesium, and calcium; prepare the concentration of each element to be measured according to the concentration of each element to be measured in the zinc-strontium alloy. To a high standard solution, introduce the standard solution into the ICP emission spectrometer, measure the emission light intensity corresponding to the different concentrations of each element to be measured with the analysis line corresponding to each element, and draw a standard curve; introduce the analysis solution into the ICP emission spectrometer, and measure The emitted light intensity corresponding to each analyte element is determined according to the standard curve to determine the content of each analyte element. The invention only needs one solution to detect the content of required elements at the same time, the preparation process of the test solution is simple, the detection process is simple and fast, the detection result has good stability, less interference and high accuracy.

Description

technical field [0001] The invention relates to a method for detecting the contents of strontium, iron, barium, magnesium and calcium in a zinc-strontium alloy, belonging to the field of detection of zinc-strontium alloy elements. Background technique [0002] In the detection field of element content, the detection of strontium, iron, barium, magnesium, and calcium content in zinc-strontium alloys often uses classical chemical analysis methods and atomic absorption spectrometry. Each time a sample is dissolved, only one element can be determined, and a variety of chemical reagents must be added from the sample dissolution to the final analysis, and a series of chemical reactions must be performed, which will inevitably lead to a cumbersome operation process, and each step may introduce errors. The result is slow analysis and not necessarily high accuracy. [0003] The classic detection methods currently used have the following disadvantages: [0004] 1. The analysis of ea...
