适用范围：This part of ISO 14869 specifies a method for the complete dissolution, using hydrofluoric and perchloric acids, of the following elements in soils: — Al, Ba, Cd, Ca, Cs, Cr, Co, Cu, Fe, K, Li, Mg, Mn, Na, Ni, P, Pb, Sr, V, Zn. This procedure may be appropriate for the subsequent determination of other elements provided their concentrations are high enough relative to the sensitivity of the methods of measurement. The low acid concentration of the final solution allows the use of a large range of analytical devices and the volatilization of silicon simplifies analytical procedures.
