Method for analyzing ludwigite through X-ray fluorescence powder tableting method

Abstract

The invention relates to a method for analyzing ludwigite through an X-ray fluorescence powder tableting method. The method comprises: (1) establishing a standard curve by using ludwigite having known contents of various elements, wherein the emission intensities of elements of a sample tablet is determined with an X-ray fluorescence spectrometer, the emission intensities of various elements are obtained by measuring a series of internal control standard samples, the mass percentage contents of various elements in the sample are combined, and a straight line associated with the sample element content and a linear equation thereof are regressed by using the least square method; and 2) determining ludwigite to be determined, wherein the emission intensities of the elements of the sample tablet are determined with the X-ray fluorescence spectrometer, and the obtained linear equation for the element content is used to calculate the mass percentage contents of various elements in the sample tablet to be determined. According to the present invention, the elements contained in the ludwigite are analyzed and detected by using the X-ray fluorescence powder tableting method, such that the advantages of high accuracy, short examination period, simultaneous multiple element determination, low examination cost, and low environmental pollution.

Description

technical field [0001] The invention relates to the technical field of chemical inspection, in particular to a method for analyzing boronite by X-ray fluorescence powder tableting method. Background technique [0002] Experiments have proved that adding a certain proportion of boron-containing additives to sinter can effectively improve the grade, alkalinity, strength and other properties of sinter, so as to achieve the purpose of smooth and smooth operation of the blast furnace and reduce the consumption of solid fuel in the blast furnace. Ferroboron or boronite is generally used as an additive, and boronite is an ideal choice in terms of cost. [0003] In addition to boron, TFe, SiO 2 , CaO, MgO, Al 2 o 3 , P, S component detection, the existing national standard GB / T 3653.3 boron chemical analysis method perchloric acid dehydration gravimetric method to determine silicon content; GB / T 3653.4 boron iron aluminum content determination EDTA titration method; Iron chemica...

Problems solved by technology

[0005] Using the conventional wet chemical method to analyze the above elements, the labor intensity is high, and the analysis period of two people's joint inspection operation is more than 6 hours, and the chemical reagents will pollute the environment.

In the current situation that there are no national standards or enterprise standards for the detection of various components of mafic ore, it is necessary to develop a fast, accurate, and less environmental pollution testing method to meet the needs of the testing work
