Wastes analysis
Passport of wastes is based on the composition and properties of the wastes, estimation of their danger. X-ray fluorescence method solves the problem of composition determination of mineral wastes, as well as ash and coke from garbage burning. Elements from Mg to U can be determined in the range from n*0,001% up to 100%.
The sample preparation consists of sample material drying to constant mass, grinding to the particle size about 50 micron, dilution 5-10 times with boron acid and pressing in pellets, which are analyzed in a spectrometer according to the chosen program. Dilution of wastes with boron acid helps to make the same matrix for various wastes and run analysis with the same calibration curve for various wastes.
Two samples of the same sample material are analyzed. Grinded sample material is pressed in pellets, which are analyzed in a spectrometer according to the chosen program. All elements are determined from the sample.
