DIN ISO 22036:2009 Soil quality - Determination of trace elements in extracts of soil by inductively coupled plasma - atomic emission spectrometry (ICP-AES) (ISO 22036:2008); English version of DIN ISO 22036:2009-06
This International Standard describes the determination of trace elements in digests or extraction solutions
from soil by inductively coupled plasma-atomic emission spectrometry (ICP-AES) for 34 elements (see
Table 1 ).
This multi-element determination method is applicable to soil extracts obtained with aqua regia in accordance
with ISO 11466, with DTPA in accordance with ISO 14870 or other weak extractants, or soil extracts for the
determination of total element contents using the acid digestion method of ISO 14869-1 or the fusion method
of ISO 14869-2.
The choice of calibration method depends on the extractant and can be adapted to the extractant
concentration.
