Abstract:
A new concept of on-line hollow fiber membrane liquid phase microextraction (HFLPME)
similar to in-tube solid-phase microextraction was investigated. The target analytes
was extracted and eluted inside the lumen of the HF membrane. In this work, on-line HFLPME
was developed for the salicylic acid (SA) in drug samples. SA in aqueous solution was
fed inside the lumen and extracted into octanol as organic solvent impregnated in the pores of
the HF membrane via diffusive mass transfer. After extraction, SA was eluted with NaOH as
the acceptor and simultaneously hydrolyzed to salicylate anion. The acceptor solution was
then reacted with Fe3+ to form violet colored complex determined by UV-Vis spectrometer at
525 nm. The extraction flow rate, elution flow rate, extraction time and concentration of
NaOH were investigated and optimized. Under optimized conditions, the linearity in the
range 0.152.00 μg mL-1 (R2=0.999) and the limit of detection of 0.18 μg mL-1 were
achieved. The enrichment factor of 95 was obtained. The method was successfully applied to
a keratolytic solution sample and the recovery of spiked sample (at SA 0.25 μg mL-1) was
100.1 %.
