| Abstract: | 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. |
| Keywords: | ICP\|AES Pig's Liver Pork Rare Earth Elements P 507 \|Extraction Chromatograph Resin |
