A polydimethylsiloxane/deep eutectic solvent sol-gel thin film sorbent and its application to solid-phase microextraction of parabens

Justyna Werner et al.

Summary: A novel, efficient, and reproducible thin-film solid-phase microextraction method was developed for preconcentration of parabens from environmental samples. The method utilized polydimethylsiloxane/deep eutectic solvent sol-gel as the coating material. New sorbent materials consisting of polydimethylsiloxane with nine new synthesized deep eutectic solvents were prepared by the sol-gel method. Among the obtained compounds, a sorbent consisting of trihexyltetradecylphosphonium chloride and n-docosanol in a molar ratio of 1:2 mixed with polydimethylsiloxane showed the highest efficiency in the extraction of parabens. The method demonstrated good precision and recovery when applied to river and lake water samples.
