Abstract

The invention relates to an analysis method for the occurrence state of Re in sedimentary rocks, belongs to the technical field of Re element analysis, and solves the problems of cumbersome operation, low intelligence and inaccurate testing in the existing analysis process. The steps include: using thermoplastic resin as a sample pad, grinding the sample padded with thermoplastic resin, and spraying gold on the surface of the ground sample; obtaining a scanning electron microscope image of the sample through a scanning electron microscope, and determining the mineral distribution and shape of the sample. The surface characteristics of the surface of the Re element are determined by using the X-ray energy spectrometer to detect the total chemical composition of the components in the target area, combined with the scanning electron microscope photos to determine the surface scanning target area of ​​the Re element; the Re element surface is scanned by the laser ablation system and the inductively coupled plasma mass spectrometry The target area is scanned by laser point ablation, and the scanned data is recorded; the two-dimensional distribution image of Re element is drawn according to the scanned data; the scanning electron microscope image and the two-dimensional distribution image of Re element are compared to confirm the occurrence state of Re in the scanned target area.

Description

technical field [0001] The invention relates to the technical field of Re element analysis, in particular to a method for analyzing the occurrence state of Re in sedimentary rocks. Background technique [0002] Rhenium (Re) is an element of the seventh group of the sixth period of the periodic table. It has high-quality properties such as corrosion resistance, high temperature resistance, and catalysis. It is widely used in thermoelectric alloys, petrochemical catalysis, and environmental protection. Replacing emerging metals, 80% of rhenium is used in the manufacture of superalloys for aero-engines, which have high application value and are called "strategic metals". As the economy and aerospace technology continue to develop, rhenium demand will continue to rise. [0003] However, the abundance of rhenium in the crust is very low (0.7 × 10 -9 , Vinogradov, 1962), the content of Re in most rocks and minerals is in the pg-ng range, such as the average upper crust is less t...
