GB/T 24997-2010 "Paper, board and pulps — Determination of cadmium content — Atomic absorption spectrometric method" specifies the determination of cadmium content in paper, board, and pulps using flame or graphite furnace atomic absorption spectrometry. This method is applicable to samples containing recycled fibers digested by wet digestion with nitric acid. After digestion of the test sample, the detection is carried out according to the method, with clear requirements for detection limits and precision. References are made to standards such as GB/T 450 and GB/T 462 to ensure the reliability of cadmium content detection results.
