摘      要：A method for determination of trace rare earth elements in biological sample by ICP-AES with tungsten-spiral electrothermal vaporization(TETV-ICP-AES)sampling has been developed in this work. Several influencing factors including desolvation and vaporization parameters,carrier gas flow rate and ma- trix effect were investigated in *** optimal experimental conditions,the detection limits for La,Nd, Gd,Dy,Ho,Yb,Lu and Y were obtained in the range of 10^(-9)～10^(-11) g,and they are comparable to and,in most instances,better than those for the GFAAS and conventional pneumatic *** precision(RSD)obtained for this method is less than 6%.
