GB/T 17593.2-2025 Textile — Determination of heavy metals — Part 2: Inductively coupled plasma-optical emission spectrometry (ICP-OES) and inductively coupled plasma-mass spectrometry (ICP-MS)
WARNING: Persons using this document shall be familiar with normal laboratory practice. This document does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any national regulatory conditions.
1 Scope
This document describes the determination of 12 extractable heavy metals, including lead (Pb), copper (Cu), zinc (Zn), arsenic (As), cadmium (Cd), chromium (Cr), cobalt (Co), nickel (Ni), mercury (Hg), antimony (Sb), selenium (Se), and barium (Ba), in textiles by inductively coupled plasma-optical emission spectrometry (ICP-OES) and inductively coupled plasma-mass spectrometry (ICP-MS)
This document is applicable to various textiles.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
GB/T 3922 Textiles - Tests for colour fastness - Colour fastness to perspiration
GB/T 6682-2008 Water for analytical laboratory use - Specification and test methods
3 Terms and definitions
No terms and definitions are listed in this document.
4 Principle
The samples are extracted and filtered with acidic sweat, and then detected by an inductively coupled plasma-optical emission spectrometer. The emission intensifiers of each heavy metal element are determined at the corresponding wavelengths, and quantified by the external standard method.
Alternatively, after filtration of the extract, it can be detected by an inductively coupled plasma-mass spectrometer. Qualitative analysis is conducted based on the specific mass number of the element (mass-to-charge ratio, m/z), and quantitative analysis is carried out using the internal standard method.
5 Reagents and materials
Unless otherwise specified, reagents used in the analysis shall be of recognized superior purity.
5.1 Water: Grade 2 water, as specified in GB/T 6682-2008.
5.2 Concentrated nitric acid: with a mass fraction of 65% to 68%.
5.3 Nitric acid solution (1+19): with a volume fraction of 5%. Take 50mL of concentrated nitric acid (5.2), dilute it with water, make up to 1000mL, and shake well.
5.4 Nitric acid solution (1+99): with a volume fraction of 1%. Take 10mL of concentrated nitric acid (5.2), dilute it with water, make up to 1000mL, and shake well.
5.5 Acidic sweat: prepare acidic sweat in accordance with GB/T 3922. The test solution shall be prepared and used immediately.
