Abstract

The invention provides a method for detecting silicon dioxide, aluminum sesquioxide, calcium oxide and magnesium oxide in acetylene sludge. The detection method comprises the steps that 1, a sample to be detected is mixed with mixed flux, and then high temperature melting is conducted, and after the mixture is cooled, a glass sheet is obtained, wherein the weight ratio of the mixed flux to the sample to be tested is (17-18): 1, the mixed flux comprises lithium tetraborate and lithium metaborate, the weight ratio of lithium tetraborate to lithium metaborate is (2.9-3.1): 1, and the high temperature melting temperature is 1000-1100 DEG C; 2, fluorescence intensity of silicon, aluminum, calcium and magnesium in the glass sheet is detected through a fluorescence spectrophotometer, and according to a predetermined standard curve of the fluorescence intensity and the element content, the content of silicon, aluminum, calcium and magnesium in the sample to be tested is obtained, and the content of silicon dioxide, aluminum sesquioxide, calcium oxide and magnesium oxide is further obtained. The detection method is small in environmental pollution, fast, convenient and easy to operate and short in cycle; the detection and analysis requirements can be completely met, and the detection result is high in accuracy and precision.

Description

technical field [0001] The invention relates to the technical field of metallurgical analysis, in particular to a method for detecting silicon dioxide, aluminum oxide, calcium oxide and magnesium oxide in carbide slag. Background technique [0002] Calcium 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 manufacture 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. [0003] The exact content of silica, alumina, calcium oxide and magnesium oxide in carbide slag plays a very important role in its field of application. The existing detection methods either have the problems of cumbersome operation and long cycle...
