Abstract

Sulfonated microphere material based on crosslinked polystyrene was synthesized by emulsification polymerization, the polymerization yield was of 75 % ± 5 % and the size of microspheres was ranging from 30–180 µm. In order to obtain the suitable capacity for the enrichment of aromatic amines (1.0 meqv/g) the condition for sulfonation process were derived from the model based on an experimental design. The products were used as a stationary phase in solid phase extraction (SPE) to enrich 18 aromatic amines derived from banned azo dyes in textile. In this study, an analytical method has been developed, with LOQ of 2 ppm. The correlation coefficient R2 of the cabliration curve was ≥ 0.9997, most of the aromatic amines had the recoveries > 80 % and RSD < 5 %. In addition, a comparison between obtained results by the developed method and those by international standard methods BS EN 14326-1: 2012 and BS EN 14326-3:2012, was also done.
