Elemental analysis of one rupee Indian coins by using EDXRF technique

Rajive Kumar, Anita Rani, Ram Mehar Singh

Abstract


Elemental analysis of some Indian coins of one rupee has been carried out by Energy Dispersive X-ray Fluorescence (EDXRF) technique which is non destructive, rapid and multi elemental in nature. The present investigation has been made for coins of different years for their elemental compositions with EDX-720 spectrometer equipped with Si(Li) detector having energy resolution 165 eV at 5.9 keV Mn K X-rays. This study observed the presence of Cu, Ni, Fe and Cr as the major elements.


Keywords
