Abstract
In this research, cotton fabric modified with polyamidoamine dendrimer was prepared by chemical method and in order to increase the extraction efficiency of cotton fabric. Before modifying the fabric with dendrimer, an activation step of the functional groups of the fabric was performed by (3-aminopropyl)triethoxysilane. The prepared adsorbent was used in thin film microextraction of Anthracene, Fenthion, p,p'-DDT, BBP and Tetradifon along with Gas chromatography-Mass spectrometer. To obtain the maximum efficiency of the synthesized adsorbent, the parameters of pH, type of desorption solvent, volume of desorption solvent, desorption time and extraction time were optimized. The dynamic linear...
