- Abstract
- An express and environmentally safe method has been developed for microextraction of furan derivatives from transformer oil for their determination by high-performance liquid chromatography with spectrophotometric detection in the ultraviolet region of the spectrum. Various hydrophilic eutectic solvents have been studied as extractants for the implementation of dispersion liquid-liquid microextraction with vortex dispersion. It was found that the highest values of the degree of extraction (from 85 to 96 %) are provided by a three-component eutectic solvent based on choline chloride, acetic acid and water. The rapid spontaneous phase separation made it possible to eliminate the centrifugation stage. Detection limits (3σ) from 1 to 5 micrograms/l have been reached.
