| 摘 要： | 本文研究了不同种类树脂对Te的吸附能力,提出了在3mol/L HCl介质中,用M_(17)二甲胺树脂吸附,然后用水洗脱的新途径,使Te有效且无污染地得到分离和富集,实现了原子荧光测定地质试样中ppb级痕量Te。经地矿部标准参考样GSR7-12考察,分析结果与推荐值相符。

| Abstract: | Adsorbabilities of various types of resins for tellurium were studied. A new effective method for the separation and preconcentration of tellurium was suggested. Tellurium was adsorbed by M17 dimethylin resin in 3mol/L HCl medium and then eluted by water without any contamination. Determination of ppb level of Te in geological samples by atomic fluorescence spectrometry (AFS) was achieved. The analytical results are in good agreement with the recommended values for GSR 7-12. |
