Embodiment Construction

[0023] The specific embodiment of the present invention is described below in conjunction with accompanying drawing:

[0024] The method steps of this specific embodiment are as figure 1 As shown, the main method flow is: dissolve most of the samples with hydrochloric acid (1+1), filter the solution, wash the residue, transfer the solution to a 250mL volumetric flask, dilute to the mark with water, and shake well. The plasma spectrometer is used for measurement, and the content of the analytical elements in the sample is obtained according to the calibration curve prepared by the standard solution.

[0025] Main instruments and working parameters:

[0026] ICP-OES: Produced by PE Company in the United States, OPTIMA5300DV two-way observation type full-spectrum direct-reading plasma spectrometer, solid-state detector (CCD), wavelength range 190-780nm, echelle grating, gem cross nebulizer, SCOTTON fog chamber, high The swirling spray chamber was used for the concentration, the...

Abstract

The invention discloses a method for measuring the content of silicon dioxide, aluminum oxide and magnesium oxide in carbide slag, belonging to the technical field of metallurgical analysis methods. The purpose is to provide a detection method with low pollution, fast speed, low detection limit and saving manpower and material cost for measuring the content of silicon dioxide, aluminum oxide and magnesium oxide in carbide slag. The main method flow is: use hydrochloric acid ( 1+1) Dissolve most of the samples, filter the solution, wash the residue and transfer the solution to a 250mL volumetric flask, dilute to the mark with water, and shake well. The plasma spectrometer is used for measurement, and the content of the analytical elements in the sample is obtained according to the calibration curve prepared by the standard solution. The determination method of the invention can be used for rapid determination of the content of silicon dioxide, aluminum oxide and magnesium oxide in carbide slag.

Description

technical field [0001] The invention specifically relates to a method for measuring the content of silicon dioxide, aluminum oxide and magnesium oxide in carbide slag, and belongs to the technical field of metallurgical analysis methods. Background technique [0002] Carbide slag is the waste residue with calcium hydroxide as the main component after the hydrolysis of calcium carbide to obtain acetylene gas. The use of calcium carbide slag can replace limestone to make cement, produce chemical products, produce building materials, and be used for environmental governance. Effective use of calcium carbide slag can not only Bring good economic benefits, environmental benefits, social benefits, and can realize turning waste into wealth. Among them, the exact content of silicon dioxide, aluminum oxide, and magnesium oxide plays a very important role. At present, there is no detection method for silicon dioxide, aluminum oxide, and magnesia in carbide slag in the national standa...
