This study developed green vortex-assisted deep eutectic-based liquid phase microextraction for preconcentration and separation of malachite green from water samples prior to determination with a UV-visible spectrometer. The prepared deep eutectic solvent contains di 2-ethyl hexyl phosphate and decanoic acid with a mole ratio of 1:2 as the extraction solvent. The influential parameters including pH, temperature and vortex time, sample volume, and ionic strength were optimized, and the optimum values of 6, 30 ºC, 30 s, and 20 ml, and without adding salt in which the extraction efficiency of 99.66 % was achieved. Moreover, at optimum conditions, the analytical performance of the method was evaluated. the limits of detection and quantification (defined as 3Sb/m and 10Sb/m, respectively) of 3.0 µg l-1 and 10.0 µg l-1 were obtained for malachite green (MG). The linear dynamic ranges of 10-600 µg l-1 and the correlation coefficients (r2) of 0.9936 were attained. Moreover, an enrichment factor of 63.1 was obtained. The relative standard deviation (%) for 100 µg l-1 of MG solution was 2.5 which showed high precision of the process. The novel combination of green vortex-assisted deep eutectic-based liquid phase microextraction and diethyl hexyl phosphate and decanoic acid represented high potential for application in real samples in which the method was successfully applied in water samples with high relative recoveries of 93.0-102.2% which confirms significant capability of the proposed method.
