Description / Abstract:
This International Standard specifies a method for the
determination of traces of cadmium in all types of paper, board and
pulp, including products containing recycled fibre, that can be
wet-combusted in nitric acid as specified in this International
Standard.
The lower limit of the determination depends on the equipment
used and is normally about 10 μg/kg. Cadmium present in pigments
and fillers that do not dissolve in nitric acid under the
conditions of this test may not be determined quantitatively.
NOTE It has been claimed that the dissolution of cadmium from
pigments other than calcium carbonate is incomplete by a few
percent.
