Diethyl carbonate as green extraction solvent for chlorophenols determination with dispersive liquid-liquid microextraction.

Abstract

The principles of green analytical chemistry indicate that the search for greener organic solvents for extraction applications is crucial. In this study diethyl carbonate (DEC) is proved to be green solvent, as it is relatively nontoxic, obtainable from renewable resources and it is biodegradable. Here it is applied as extraction solvent for chlorophenols determination in water samples with dispersive liquid-liquid microextraction. The multiobjective optimization for 7 chlorophenols is done with design of experiment combined with Derringers desirability function. The optimized parameters on extraction step are 300 µL of DEC volume, 0.5 mL of methanol, 8 mL of water sample and 7.5% of inorganic salt addition. The values of LOQ are from 0.01 to 0.3 µg L-1, CVs are between 7.1-17.3 % for 7 CPs. In this study DEC is proved to be promising, green solvent, applicable in analytical extractions.
