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

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.
