摘要本研究建立了一种以NOBIAS PA1螯合树脂为富集手段，结合电感耦合等离子体质谱（ICP-MS）测试富含有机碳的咸水湖泊中Mn、Fe、Co、Ni、Cu和Zn的分析方法.该方法首先使用UV/H₂O₂法对湖泊水体进行消解，去除有机络合作用对Co和Cu的干扰；然后对咸水中的微量元素进行预富集，并使用醋酸铵去除树脂上吸附的盐类；最后使用HNO₃洗脱样品并用ICP-MS进行测试.结果表明，在pH值6.35±0.30的情况下，不同微量元素流程空白值为0.49~6.43ng/kg；检出限为0.17~4.55ng/kg；样品的回收率为99%~102%.该方法用于西藏雅根错、色林错、昂仁金错的测试结果显示，该方法加标（内标元素In）回收率>99%；样品（n=3）的相对标准偏差<5%.本方法适用于内陆湖泊尤其是富含有机质的咸水湖泊（包括盐湖）微量元素分析.

Abstract：A novel method was developed using a NOBIAS PA1 chelating resin with an inductively coupled plasma mass spectrometry (ICP-MS) measurement for Mn, Fe, Co, Ni, Cu, and Zn in organic-rich saline lakes. First, H₂O₂ was added to the samples which were subsequently irradiated with a digester containing three low-pressure ultraviolet lamps. This UV/H₂O₂ method could destroy the organic ligands of Co and Cu in water to reduce their interference. Then, the trace metals were pre-concentrated through a chelating resin column. The column was rinsed with an NH₄AC solution to remove the loaded salts. Finaly, the trace metals were eluted with HNO₃ solution and analyzed by ICP-MS. Results showed that the procedural blanks and detection limits of the trace elements were 0.49~6.43 ng/kg and 0.17~4.55 ng/kg, respectively, at a pH of 6.35 ±0.30. All trace metals were quantitative, and their recovery rates were 99%~102%. The results from the application of this method to Yagen Co Lake, Selin Co Lake, and Angren Jin Co Lake in Tibet showed that the recovery rates of Indium internal standard were >99%, and the relative standard deviations of the samples (n =3) were less than 5%. These findings suggests the method developed in this paper could be used to analyze trace metals in inland lakes, especially in organic-rich saline lakes (including salt lakes).
