| Abstract: | The matrix effect of tantalum on the determination of Al, Ca, Cr, Cu, Fe, Mg, Mn,Mo, Nb, Ni, Ph, Sn and Ti by ICP-AES was studied. The influence mechanism of carrier gas flow, forward power, distance of warp direction and observation height on the matrix effeet of tantalum was discussed. The matrix interferences of tantalum on the determination of trace elements were minimized by optimizing instrumental parameters. |
