Area of Science:

  • Analytical Chemistry
  • Environmental Science
  • Materials Science

Background:

  • Parabens are common preservatives found in personal care products, raising concerns about their environmental presence.
  • Effective methods for selective enrichment and detection of parabens in environmental matrices are needed.

Purpose of the Study:

  • To develop a novel high-throughput analytical platform for selective paraben enrichment and removal.
  • To establish a sensitive method for paraben analysis in environmental water samples.

Main Methods:

  • Construction of a high-throughput array analytical platform using derived β-cyclodextrin supramolecular imprinted polymer (SMIP) fibers.
  • Integration of the SMIP fiber array with High-Performance Liquid Chromatography (HPLC) for detection.
  • Utilizing the host-guest inclusion effect of β-cyclodextrin for enhanced adsorption.

Main Results:

  • The SMIP fiber array demonstrated abundant imprinting sites and improved adsorption capacity for parabens.
  • A specific and sensitive recognition method was developed with a low limit of detection (0.003–0.02 µg/L).
  • The method exhibited good linearity (R > 0.9994) over a wide concentration range (0.01–200 µg/L).

Conclusions:

  • The developed SMIP fiber array platform offers high-throughput adsorption and potential for effective paraben monitoring in water.
  • This approach provides a reliable reference for analyzing other pharmaceutical and personal care product pollutants in the environment.
