中文摘要	in this work, a method was established for the determination of impurities in high purity tellurium by inductively coupled plasma mass spectrometry (icp-ms) after fe(oh)(3) coprecipitation. after comparison of coprecipitation ability and separation efficiency between fe(oh), and al(oh)(3), fe(oh)(3) was chosen as the precipitate. a separation factor of 160 for 200 mg tellurium was obtained under conditions of ph 9 and 2 mg of fe3(+). the 13 elements, such as bi, sn, pb, in, tl, cd, cu, co, ni, zn, ti, be and zr, could be almost completely coprecipitated under these conditions. in addition, te memory effect imposed on the icp-ms instrument was assessed, as well as te matrix effect that caused the low recovery of ga, as, sb and v in real sample was discussed. finally, the method was evaluated through recovery test and was applied to practical sample analysis, with detection limits of most of the elements being below 0.15 mug g(-1) and r.s.d. below or at approximately 10%, which indicated that this method could fully satisfy the requirements for analysis of 99.999% similar to 99.9999% high purity te.
