| Abstract: | A comprehensive analytical method based on liquid chromatography-tandem electrospray ionization mass spectrometry has been developed for the determination of carcinogenic aromatic amines in textiles.Textile samples were reduced with sodium dithionite in citrate buffer solution.The reduced solution was extracted by diatomite,and diatomite was eluted with diethyl ether.The gathered solution was evaporated,then flushed to dry with nitrogen and fixed with 1 mL of methanol.After the chromatographic separation on... |
