Summary
A new analytical platform using supramolecular imprinted polymer (SMIP) fibers selectively removes parabens from water. This high-throughput method offers sensitive detection for environmental monitoring.
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.
