Abstract

Magnetic nanoparticles MNPs prepared via thiolene click chemistry and containing both diol and octadecyl groups are shown to possess both hydrophobic and hydrophilic functionalities They display excellent dispersibility in water and also are capable of extracting nonsteroidal antiinflammatory drugs NSAIDs from water samples The MNPs can be magnetically separated and the NSAIDs eluted with acetonitrilewater 91 vv and submitted to high performance liquid chromatographic analysis Extraction variables such as the kind of ionpairing reagents amount of MNPs pH of sample solution extraction and desorption time volume of desorption solvent and salt addition were optimized Under optimum conditions the method has a wide analytical range from 5 to 800 ng∙mL‾1 good reproducibility with intraday and interday relative standard deviations of 192  for n = 6 and low detection limits of 032 to 144 ng∙mL‾1 for water samples The results demonstrate that the material possesses good water compatibility thus warranting ease of operation and good reproducibilityThe waterdispersible C18/diolFe3O4 MNPs were prepared via “Thiolene” click reaction The material can be used as MSPE sorbent to extract nonsteroidal antiinflammatory drugs from river water Satisfactory results were obtained with convenient operation and good reproducibility
