The geothermal energy is a new energy which has been widely developed and applied. Fof the further stuoly, the test is carried out by acidification of geothermal water, and then eight trace elements (Fe, Mn, Li, Cu, Pb, Zn, Cd and Cr) in geothermal water are simultaneously determined by ICP-AES method. The detection limit of this method is 0.5~2.4μg/L, the precision(n=6) of sample is 0.59%~4.65%, and the recovery of standard adding is 94.22%~105.51%, the result is quite satisfied. It provides a quick and accurate method for the determination and analysis of trace elements in geothermal water.
