M17树脂分离富集原子荧光测定岩矿中痕量碲

AFS Determination of Trace Te in Geological Samples after Separation and Preconcentration by M_(17) Resin

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
