| Abstract |
A green approach using chitosan solution as a novel bio-dispersive agent for the dispersive liquid–liquid
microextraction (DLLME) of trace amounts of Cu(II) in edible oils is presented. An emulsion was formed
by mixing the oil sample with 300 mL of 0.25% (w/v) chitosan solution containing 200 mL of 6mol L1 HCl.
Deionized water was used to induce emulsion breaking without centrifugation. The centrifuged Cu(II)
extract was collected and analyzed using an inductively coupled plasma–optical emission spectrometer.
The detection and quantitation limits were 2.1 and 6.8 mg L1, respectively. Trace amounts of Cu(II) in six
edible oil samples were tested under optimum conditions for DLLME, with a recovery ranging from 90.3%
to 109.3%. Therefore, the new dispersive agent in DLLME offers superior performance owing to the nontoxic
nature of the solvent, short extraction time, high sensitivity, and easy operation. |
