| Abstract: | Using preconcentration-separation technique with P507-extraction chromat ograph resin,an inductively coupled plasma atomic emission spectrometry method for determination of ultra trace rare earth elements in the pig's bones and teeth was developed.La, Ce, Pr, Nd, Sm, Y in the samples were detected without the in terference of Ca & P.The detection limits of the method were in the range of 2.0 —4.4ng/g.The recovery rates and precision of the method were in the range of 80 %—90% and 3.1%—9.1% respectively.The method can be used to determine rare earth elements in market pigs. |
