Abstract Scope |
Quantitative and qualitative chemical analyses are of great importance in the characterization of materials and in mineralogy, in order to determine the content of elements present in minerals; the equipment used for this kind of analysis is very expensive and sophisticated. Image segmentation can provide a semi-quantitative analysis of the elemental content of the mineral surface. In the present work, the semi-quantitative analysis of fluorite was carried out using Atomic Absorption Spectrophotometry, X-ray dispersive energy spectrometry and the comparison with image segmentation was made, matching the percentages of calcium and fluorine in the three methods. The analysis of the images was based on the intensity of the colors to determine the content of each element present in the mineral, subsequently the method of functional approximation and interpolation was used so that it can be an economic form, precise and easy to use for determining semi-quantitative composition of mineral surfaces. |
