X-RAY RADIOMETRIC METHOD OF DETECTING Eu, Gd, Tb, Dy IN SOIL Russian patent published in 2012 - IPC G01N23/223 

FIELD: chemistry.

SUBSTANCE: invention can be used to detect rare-earth metals Eu, Gd, Tb and Dy in soil using an X-ray radiometric method. The method involves preparing artificial reference samples with known concentration of analysed and interfering elements for plotting calibration curves, wherein intensity of analytical K_α1-lines is the procedure of deconvoluting the spectrum which overcomes the effect of layover of the β-component of lines of interfering elements on them.

EFFECT: possibility of designing a cheap, easy to implement alternative X-ray radiometric method of analysing elements Eu, Gd, Tb and Dy.
