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.
