Abstract

Solid-phase extraction (SPE) and UV/Vis-spectrometer are acknowledged as economical and efficient technique analytical techniques and applied in analyzing target organic compounds in water and other aqueous samples. The present study suggested imidacloprid (at 270nm) and bisphenol-S (at 259nm) can be detected and quantitatively measured via UV-vis spectrometer. The assay was linear with a good coefficient of correlation for both imidacloprid (R2 = 0.9992) and bisphenol-S (R2 = 0.9996). Based on SPE coupled with UVspectrometer, the recovery of IMP and BS were achieved at 93-97% and 86-116% respectively, which are close to that achieved by SPE coupled with liquid chromatography-mass spectrometer (LC-MS) analysis; 84-102% for imidacloprid and 83-92% for bisphenol-S.
