Soil quality. Dissolution for the determination of total element content - Dissolution by alkaline fusion

•

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

— 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.
