Improvement of XRF analysis for trace elements in silicate

Analytical techniques of eleven trace elements (Nb, Zr, Y, Sr, Rb, Zn, Cu, Ni, Cr, V and Ba) in silicate rocks using XRF with flux-fused disks were improved. Lil was used as a remover instead of LiBr. A radio high frequency furnace was used to melt a rock sample
