Determination of 9 Migratory Heavy Metals in Textiles by Inductively Coupled Plasma Mass Spectrometry

Nine migratory heavy metals in textiles, including Sb, As, Pb, Cd, Cr, Co, Cu, Ni, Hg were determined by inductively coupled plasma mass spectrometry (ICP-MS). The detection limits are in the range of 0.01—0.49 μg/kg, the RSDs are less than 6.1%, and the recoveries of 9 migratory heavy metals are in the range of 90.0%—109.6%, which meet the determination requirements. 9 migratory heavy metals in 4 product classes of textiles, including products for babies, products with direct contact to skin, products without direct contact to skin and decoration materials were determined by ICP-MS. The results are satisfactory.
