Embodiment 1

[0071] A method for quickly measuring major, minor and trace components in granite by X-ray fluorescence spectroscopy, comprising the following steps:

[0072] 1) Sample preparation: After mixing the sample and the mixed flux evenly, add lithium nitrate solution, after pre-oxidation; use ammonium iodide as the release agent, heat up and melt; pour the molten material into the preheated mold, cool and form Take out the fusing chip, mark it and put it in a desiccator for testing;

[0073] 2) Selection of a series of calibration samples: select certified reference materials of granite, granodiorite, quartz sandstone, shale, basalt, water system sediments, soil, potassium feldspar, albite, siliceous sandstone, kaolin, And based on these certified standard materials, two or more standard materials are mixed in any proportion, the number of calibration samples is increased, and the content of each element is distributed in a certain gradient, so as to obtain a series suitable for gr...

Abstract

The invention belongs to the field of fluorescence spectrum detection, and particularly relates to a method for rapidly measuring major, minor, and trace components in granite by an X-ray fluorescencespectrum. The method comprises the following steps: preparing a sample by using a fusing method, after performing lithium nitrate preoxidation on the sample, selecting a lithium tetraborate and lithium metaborate mixed reagent of which a mass ratio is 12:22 as a fusing agent, using ammonium iodide as a releasing agent, and preparing a fusing piece. A standard substance, such as the granite, is used as a calibration sample, and an elemental analysis range is further enlarged by artificially synthesizing the sample, the absorption enhancement effect between elements is calibrated through a changed theoretical Alpha-coefficient method, and an X-ray fluorescence spectrum method for 15 components of silicon dioxide, aluminum oxide, potassium oxide, sodium oxide, ferric oxide, calcium oxide, magnesium oxide, manganese oxide, phosphorus pentoxide, titanium dioxide, barium, strontium, sulfur, rubidium and zirconium in the granite is established. The method has the advantages of simple pretreatment, rapid detection speed, low cost, simultaneous analysis of major, minor, and trace elements and the like, and is capable of greatly improving the detection efficiency.

Description

technical field [0001] The invention belongs to the field of fluorescence spectrum detection, and in particular relates to a method for rapidly measuring major, minor and trace components in granite by X-ray fluorescence spectrum. Background technique [0002] The determination and analysis of the content of each element in granite is of great significance to the study of its mineralization, and it is an important basic work for geological prospecting. Granite is composed of primary, secondary and trace components such as silica, aluminum oxide, potassium oxide, sodium oxide, iron oxide, titanium dioxide, calcium oxide, magnesium oxide, phosphorus pentoxide, and manganese oxide. According to the different content of its components, traditional detection methods mainly use volumetric method, gravimetric method, spectrophotometry, atomic absorption spectrophotometry and inductively coupled plasma emission spectrometry, etc., which have long detection cycle, cumbersome operat...
