Development of new analytical methods for toxicants used in textile

Newly regulated toxicants like flame retardants, phthalates, biocides (MIT, CIT, OIT, Triclosan), ortho-phenylphenols, DMFu, and azo dyes lack certified testing methods, making detection in consumer products difficult. To address this, sensitive and rapid analytical techniques were developed for textiles, foam, leather, and plastics. Samples were extracted using an organic solvent at 60°C for 60 min with sonication, followed by centrifugation and filtration. Toxicants were analyzed using GC/MS with a DB-5MS column and helium gas or UFLC. Extraction conditions were optimized, achieving good linearity (r² ≥ 0.9995) and recovery rates of 100 ± 15%. LOQs ranged from 0.02 - 0.2 mg L⁻¹, with detected levels between 5.18 - 1798.14 mg L⁻¹. These methods effectively identified controlled substances across various matrices.
