Abstract

The invention relates to a method for detecting the element content in alloy or ore by utilizing an ICP emission spectrometer, comprising the following steps: placing the alloy or the ore in solvent,heating and leading the alloy or the ore to be dissolved fully in solution to obtain mixed solution; diluting the mixed solution to obtain test solution; selecting the optimal analysis line of each element according to the composition of substrate of the alloy or the ore; preparing a set of corresponding standard solutions with the concentration sequencing from low to high according to the concentration index of each element in the alloy or the ore; introducing the standard solutions to the ICP emission spectrometer to measure the emission light intensity of the element analysis line and to draw a standard curve; introducing the test solution to the ICP emission spectrometer to measure the emission light intensity corresponding to each element; and determining the content of each element according to the standard curve. The method can detect simultaneously the content of the required element and oxide only by one solution, therefore, the invention has simple operation, shortened measuring cycle, stable detection results with high accuracy degree.

Description

technical field

[0001] The invention relates to a method for detecting the contents of multiple elements in alloys or ores, in particular to a method for simultaneously detecting the contents of multiple elements in alloys or ores using an ICP emission spectrometer. Background technique

[0002] In the field of detection of element content, classical chemical analysis methods are often used for the detection of copper alloys, aluminum alloys, alloy steels and iron ores. For example: the analysis of iron ore, the traditional analysis method is to use high temperature alkali fusion sample, after acidification, add oxidizing agent, reducing agent, masking agent, protective agent and color developing agent to form a compound that can be accurately analyzed without interference, and then use Spectrophotometry, atomic absorption spectrometry or gravimetry are used to determine the element content in the sample; only one element can be determined for each sample dissolved, and a va...
