Abstract:
In this research nanostructural poly (o-aminophenol) was synthesized
by electropolymerization and used for solid phase microextraction
fiber procedure (SPME). Thin film of Poly (o-aminophenol) (۴ μm
thickness) was shaped by sweep potential for ۴۵ min on the surface
of stainless steel wire. Polymer was synthesized by potentiostat
procedure too. Prepared polymer by sweep potential procedure
showed nanostructures on the surface. Acetic anhydride was employed
for derivatization of bisphenol A (BPh-A) and analysis of acetylated
BPh-A was utilized by gas chromatography-flame ionization detector
(GC-FID). Affecting parameters on derivatization and extraction
such as amount of acetic anhydride, stirring rate, temperature, ionic
strength and extraction time were optimized. The limit of detection
(LOD) and relative standard divisions (RSDs%) were achieved ۰.۶
μgL-۱ and less than ۶.۸%, respectively under optimized conditions.
Finally proposed method was used for extraction of bisphenol A from
leaching of baby and drinking water bottles. Relative recovery was
achieved ۹۸% for leaching from drinking bottle. In leaching from
plastic baby bottle, bisphenol A (BPh-A) was detected in the range
۵–۱۵ μg L-۱.
