GB/T 24990-2010 Paper,board and pulps—Determination of chromium
Abstract
This standard specifies the method for determining the trace amounts of chromium in paper, cardboard, and pulp.
This standard is applicable to various types of paper, cardboard, and pulp that can be digested by dry methods or wet nitric acid methods to detect the chromium content in the samples.
The detection limit of the method depends on the instrument used. For flame atomic absorption measurement, it is generally about 10 mg/kg, and for graphite furnace atomic absorption measurement, it is generally about 50 μg/kg.
