Polymeric porous membranes as solid support and protective material in microextraction processes: A review

Polymeric porous membranes have proven to be a versatile and efficient material for microextraction processes. In analytical practice, they are used both as a solid support and as a protective medium for improved sample preparation in various analytical applications. Polymeric porous membranes offer unique advantages in microextraction due to their large surface area and controllable pore size, eliminating interfering effects from complex sample matrices and improving the selectivity of the analysis. This review summarizes key aspects of the application of polymeric porous membranes in liquid- and solid-phase microextraction, addresses challenges and advances of their implementation in the chemical analysis of food, biological and environmental samples. The novel view into the polymeric porous membranes include greenness assessment of the methods used for their synthesis as well as solvents applied during the technological process. • Polymeric porous membranes for sample preparations. • Supported liquid membrane for liquid phase microextraction. • Porous membranes as protective material for complex samples. • Application of porous membranes to food, biological and environmental samples. • Greenness assessment of the membrane synthesis technologies.
