电感耦合等离子体质谱法分析汤岗子热矿泥中微量元素

Determination of Microelements in Thermal Mineral Mud of Tanggangzi by ICP-MS

摘要: 本工作对汤岗子热矿泥中微量元素进行分析研究。采用微波消解法处理样品, 电感耦合等离子体质谱法对汤岗子热矿泥中钠、镁、锌、锰、铜、锗、钼、铬、铝、镍、汞、铅等12种微量元素进行检测与分析。结果表明, 在优化实验条件下, 方法的检出限为0.000 3~5.86 μg•L^-1, 相对标准偏差为0.91%~6.02%, 回收率为91.10%～108.0%。

Abstract: The microelements in the thermal mineral mud of Tanggangzi were digested by microwave, and were detected by inductively coupled plasma mass spectrometry (ICP-MS). The results show that the detection limits are 0.000 3—5.86 μg•L^-1, the relative standard deviations are 0.91%—6.02%, and the recoveries are 91.10%—108.0% of 12 kinds of microelements Na, Mg, Zn, Mn, Cu, Ge, Mo, Cr, Al, Ni, Hg and Pb in the thermal mineral mud of Tanggangzi.
