Scope
This part of PS 3158 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 > (3 d · V/m)
where
| w | 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, and |
| m | 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.
