BSI BS ISO 14869-2:2002

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

PUBLISH DATE 2002
BSI BS ISO 14869-2:2002

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 > (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.
