n this article, Dispersive Liquid-Liquid Micro Extraction based on the Solidification of Floating Organic drop (DLLME-
SFO) was successfully used as a sample preparation method prior to flame atomic absorption determination of trace amount
of copper in standard and wastewater samples. Several factors that may be affected on the extraction process, such as extraction
and disperser solvent, the volume of extraction and disperser solvent, effect of salt, pH of the aqueous solution and extraction
time were optimized. Under the best experimental conditions, the calibration curve was linear in the range of 0.8 ng mL
-1
- 0.5
µg mL
-1
of copper and detection limit was 0.2 ng mL
-1
in the original solution (3 Sb/m). The relative standard deviation seven
replicate determination of 0.1 µg mL
-1
copper was ±1.9%. The high efficiency of DLLME-SFO to carry out the determination
of copper in complex matrices was demonstrated. Finally, the proposed method has been applied for determination of trace
amount of copper in standard and wastewater samples with satisfactory results.
