文摘
- •
A novel DLLME-SFO method was developed for copper extraction.
- •
It was used for matrix elimination and preconcentration of copper.
- •
The accuracy of the method was verified by analysis of certified materials.
- •
The method was successfully applied to different water and food samples.
- •
The main benefits: minimum organic solvent, low cost, rapid analysis, sensitivity.
