MIL-53-PVDF mixed-matrix membrane for dispersive membrane solid-phase extraction of phenoxy carboxylic acid herbicides in environmental water sample followed by HPLC determination

Key Points

• This research aims to develop a membrane for extracting phenoxycarboxylic acid herbicides from water samples.
• Preparation of MIL-53-PVDF mixed-matrix membrane
• Application of the membrane for solid-phase extraction
• Use of HPLC for analysis of extracted herbicides
• Successful enrichment of 2,4-D, MCPA, 2,4-DP, and 2,4-DB herbicides
• Detection limits were significantly lower with the membrane extraction method
• Higher recovery rates of herbicides in environmental water samples
