Ultrasound assisted emulsification microextraction using cholin chloride based deepeutectic solvent for preconcentration and determination of vanillin by differential pulsevoltammetry

A new and simple deep eutectic solvent (DES) based ultrasonic-assisted emulsification liquid phasemicroextraction (UAE-LPME) procedure has been developed for preconcentration and voltammetricdetermination of vanillin in food products. Calibration graph was linear in the range of ۸.۰-۱۶.۰ μg/L (R۲ = ۰.۹۹۳۵)and the limit of detection was ۳.۰ μg/ml.
