| Abstract: | This Paper has discussed the effect of matrix on the signal for rare earth impurities to be determined and also studied the compensation of internal standard for the matrix effect.For different matrix elements,the optimum internal elements are inconsistent.Ga,In,I,Cs and T1 are stuitable internal standard elements in the analysis of high puity rare earths.Internal standard method is simple and effective,its precision and recoveries are statisfactory. |
