电感耦合等离子体质谱法分析汤岗子热矿泥白粉中的矿物元素

Determination of Mineral Elements in Thermal Mineral Mud fromTanggangzi Hotspring by Inductively Coupled Plasma-Mass Spectrometry

摘要: 对汤岗子热矿泥白粉中矿物元素进行分析研究。采用微波消解法处理样品，运用电感耦合等离子体质谱法对汤岗子热矿泥白粉中钠、镁、钾、钙、铁、锌、锰、铜、硒、锗、钼、铬、铝、镍、砷、汞、铅等17个矿物元素进行分析。结果表明，在优化实验条件下，方法检出限为0.0002799～14.66 μg/L，相对标准偏差(RSD,n=6)为0.18%～6.20%，回收率为91.1%～108.2%。汤岗子热矿泥白粉中含有丰富的矿物元素。

Abstract: The mineral elements in the thermal mineral mud samples from Tanggangzi hotspring were analyzed. The thermal mineral mud samples were decomposed by microwave digestion and the elements of Na, Mg, K, Ca, Fe, Zn, Mn, Cu, Se, Ge, Mo, Cr, Al, Ni, As, Hg and Pb in the samples were analyzed by inductively coupled plasmamass spectrometry (ICP-MS). The results showed that under optimum conditions， the detection limits of the method for these elements were in the range of 0.0002799～14.66 μg/L. The recovery of the method for these elements was 91.1%～108.2% with precision of 0.18%～6.20%RSD (n＝6). The results also indicated that the thermal mineral mud from Tanggangzi hotspring contained abundant of mineral elements.
