摘　　要：采用 P50 7萃淋树脂预富集分离技术 ,用 ICP- AES法测定猪肝、猪肉中痕量稀土元素 L a、Ce、Pr、Nd、Sm、Y的含量 ;本法排除了基体中 Ca、P、Fe的干扰 ,检出限为 0 .33— 0 .74 ng/g(鲜样 ) ,回收率为 84 .8%— 10 9.1% ,精密度为 4 .9%— 11%Using preconcentration\|seperation technique with P 507 \|extraction chromatograph resin,an inductively coupled plasma atomic emission spectrometry method for determination of ultratrace rare earth elements in the pig's liver and pork has been developed.La,Ce,Pr,Nd,Sm,Y in the samples were detected without the interference of Ca,Fe & P.The detection limits of the method were in the range of 0.33 %_0.74ng/g.The recovery rates and precision of the method are in the range of 84.8 %_109.1% and 4.9%_11%,respectively.
