| Abstract: | Deep-sea ferromanganese nodules were dissolved by HNO 3 -HF-HClO in a sealed container at low pressure; HF was evaporated in an open container and salts were dissolved in HCl by heating, then transferred to a 2% HNO 3 solution. Forty-one elements including Li, Be, Sc, Ti, V, Mn, Co, Ni, Cu, Zn, Rb, Sr, Y, Zr, Mo, Cd, In, Sb, Cs, Ba, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Hf, Ta, W, Tl, Pb, Bi, Th and U, were measured by inductively coupled plasma mass spectrometry (ICP-MS). Conditions and sample experiments showed that this procedure is a good experimental method with the characteristics of correct principle, clear interference, easy operation, and reliable results. The concentrations of the 41 elements could be used for resource exploration, environmental assessment, and academic research. |
