Incorporating PET-MIL-101(Fe) within cellulose acetate membrane for thin film microextraction of neonicotinoid insecticides in water.

ABSTRACT: Herein, cellulose acetate membrane modified with polyethylene terephthalate derived MIL-101(Fe) (PET-MIL-101(Fe)) was used as an extraction phase for the direct immersion-thin film microextraction method (DI-TFME) of neonicotinoid insecticides in water samples. The quantitative analysis of clothianidin, imidacloprid, thiacloprid and thiamethoxam was carried out using high-pressure liquid chromatography (HPLC-DAD). The morphological and structural characteristics of the materials were studied using transmission electron microscopy (TEM), X-ray diffraction analysis (XRD), and energy dispersive X-ray spectrometry (EDX). Under optimum conditions, acceptable analytical performance for the developed DI-TFME/HPLC-DAD method was attained. The linearity of the method ranged from 0.04 to 500 µg/L wi
