This paper descibes the determination of Rb and Sr in silicate samples by energy-dispersive X-Ray fluorescence method, in which the internal-standard method was used. The C.V. for 17 determinations were 4.6 and 3.4% for 0.1% Rb and Sr, respectively. The sensitivity of this method were 0.0003% for Sr and 0.001% for Rb.
