Determination of Mineral Elements in Thermal Mineral Mud fromTanggangzi Hotspring by Inductively Coupled Plasma-Mass Spectrometry
-
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 plasmamass spectrometry (ICP-MS). The results showed that under optimum conditions, the detection limits of the method for these elements were in the range of 0.0002799~14.66 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.
