| 摘 要： | A method for determination of trace rare earth elements in biological sample by ICP-AES withtungsten-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 detail.Under 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,inmost instances,better than those for the GFAAS and conventional pneumatic nebulisation-ICP-AES.Theprecision(RSD)obtained for this method is less than 6%.
