Description
Technical field
The present invention relates to mineralogical composition detection technique field, particularly relate to assay method and the device of carbon dioxide content in a kind of mineral.
Background technology
In mineral, the assay method of carbon dioxide content has: acid base titration, gas absorption gravimetric method, volumetric method etc.
Acid base titration ratio juris is accurately to take sample, with transfer pipet, accurately adds a certain amount of strong acid standard solution, and sample is dissolved and complete reaction, with the acid of standard solution of sodium hydroxide residual titration surplus, according to consuming alkali number, calculates carbon dioxide content.As, what in carbonate scale, the mensuration of carbon dioxide adopted is acid base titration.The method is inapplicable as Alkaline minerals material, as cement etc.
Gas absorption gravimetric determination principle is as follows: with salt acid treatment sample, the carbon dioxide that in sample, carbonate decomposition is separated out, with the alkali asbestos that are contained in U shape pipe, absorb, according to the increase of U-shaped pipe quality, obtain carbon content in coal hydrochlorate carbon dioxide content.The world, domestic mensuration cement, carbon content in coal hydrochlorate carbon dioxide are all to adopt gravimetric method at present.
Volumetric method measuring principle is as follows: with hydrochloric acid decomposing carbonate sample, decompose the gas volume producing determine carbonate carbon dioxide content by measurement.The method is quick, simple, is not suitable for analyzing the sample that simultaneously has other gases to emit.
Key reaction equation is as follows:
MeCO
3+ 2HCl=MeCl
2+ H
2o+CO
2↑ (Me representation metal ion)
After existing volumetric method assay method and device sealing, there is pressure differential in eudiometer tube and balance pipe both sides, and liquid level is poor, causes gasmetry pipe to regulate difficult zero point; In addition, during measurement, before reading, need adjustment pipe height, the defects such as complex operation.The present invention joins open to atmosphere threeway section door plug by increase, is convenient to the pressure on acid adding forward horizontal stand measure portion eudiometer tube and balance pipe both sides; By increasing tapping valve replacement adjustment pipe height, facilitate reading.
