Description
Summary:In this study, metal organic framework MIL-101 (Cr) was used as an adsorbent in the solid phase extraction of parabens before chromatographic analysis. Analytical parameters including pH, adsorption–desorption time, amount of adsorbent, elution solvents, desorption volume and salt effect were optimized. Optimum adsorbent amount and total adsorption and desorption time for determination of parabens were found to be 15 mg and only 10 min. The recovery values obtained with this method are in the range of 90.78–104.89% for water matrix and 85.19–108.35% for cosmetics. The detection limits of the HPLC method for methyl, ethyl, propyl, and butyl parabens are 0.0387, 0.0322, 0.0299, and 0.0339 ug/mL, respectively. Prior to HPLC analysis, a new, fast, inexpensive, and environmentally friendly solid phase extraction method based on vortex-assisted MIL-101 (Cr) adsorption was developed. This proposed VA-SPE-HPLC procedure was used for the extraction and determination of four different parabens from water and cosmetic samples.
