適用范圍：This part of ISO 14869 specifies a method for the dissolution of total contents for the following elements in soils:Na, K, Mg, Ca, Ti, Mn, Fe, Al, Si.This list is not exhaustive, and other elements are applicable for determination, provided— they are not lost during the fusion process,— w > (3d · V/m) wherew is the mass content of the element, expressed in milligrams per kilogram soil,d is the detection limit, in milligrams per litre, for the element and analytical method considered,3 is a conventional factor,V is the adjusted volume, in litres, of the final solution containing the dissolved sample, andm is the mass of the test portion, in kilograms,— the determination is not adversely affected by the high salt concentration in the resultant solution.The flux proposed in this method is suitable for a wide range of materials, among which soil samples are relatively easy to deal with.
