The major textile and leather products that are offered to consumers need to be safe. In order to ensure safety as per the global regulations, the allowed limit of carcinogenic amines in textile and leather products cannot be more than 20 mg/kg. There are several methods that have been used for extracting the azo dyes and analyzing them in textile and leather products. Most of these methods are polluting from high solvent usage, time consuming, laborious, and have lower recovery rates. In the present study QuEChERS method, (dispersive solid phase extraction-dSPE) method was utilized for extraction of carcinogenic arylamines from dyed leather and textile products. The released arylamines are extracted into acetonitrile using QuEChERS salt and analyzed by Ultra Performance Liquid Chromatography-Photo Diode Array (UPLC-PDA). The extracted product was further confirmed by Gas Chromatography-Mass Spectrometer (GC-MS). The method proposed in this study is novel as it eliminates all significant concerns associated with the official ISO-17234-1 &14362-1 test methods, such as use of solvents like tert-butyl methyl ether (MTBE) and the long duration of analysis. The sample preparation time is minimized from 120 min to 20 min. The developed method is easy to adopt with efficient recovery rate of arylamines in comparison to the official ISO method.
