GB/T 41523-2022 "Paper, board and pulps — Determination of total magnesium, calcium, manganese, iron and copper" is applicable to various types of paper, board, and pulps. The standard specifies two determination methods: atomic absorption spectrometry and inductively coupled plasma atomic emission spectrometry. The total content of elements includes both acid-soluble and acid-insoluble portions. It defines the detection limits for each element and standardizes the sample pretreatment, instrument operation, and result calculation procedures to ensure the accuracy of the determination results.
