Overview

Findings reveal enhanced extraction performance of alkyl- and chlorophenols using optimized MOF membranes, indicating significant environmental detection potential.

Key Points

  • This research aims to develop optimized mixed matrix membranes integrating UiO-66(Zr) for effective microextraction of target phenolic compounds from water samples.
  • Fabrication of mixed matrix membranes by combining UiO-66(Zr) MOF with polystyrene on paper supports via dip coating.
  • Optimization of several prep parameters including paper pretreatment, air-drying, MOF loading percentage, and number of coating layers.
  • Characterization of membranes followed by adsorption and desorption kinetic experiments.
  • Achieved maximum adsorption capacity of 70% in 60 minutes and fast desorption in methanol within 10 minutes.
  • Detectable limits of 21.5 μg·L−1 for phenols using the developed method with HPLC-DAD.
  • Inter-device reproducibility showed a relative standard deviation of less than 18%, indicating high consistency.
