In this work, the potential of various types of vegetable oil-based organic solvents (VOS), i.e. vegetable oils with (containing either D2EHPA or TBP, or both) and without extractants, to extract Cu(II) from aqueous solutions was investigated. The role of vegetable oils either as extractants or diluents in Cu(II) extraction was also determined

Extraction of Cu(II) from aqueous solutions by vegetable
Various types of vegetable oil-based organic solvents (VOS), i.e. vegetable oils (corn germ, canola, sunflower and soybean oils) with and without extractants (di-2-ethylhexylphosphoric acid (D2EHPA) and tributylphosphate (TBP)), were investigated into their potentiality as greener substitutes for the conventional petroleum-based organic solvents to extract Cu(II) from aqueous solutions.

Extraction of copper from aqueous solutions using plant oils
The closest technical solution is the extraction of copper from aqueous solutions with a concentration of 500 mg/DM 3 vegetable oils at pH≥4, the ratio of organic and aqueous phase a:=1:19 and the regulation of pH for a period of not more than 4.5 .
Various types of vegetable oil-based organic solvents (VOS), i.e. vegetable oils (corn germ, canola, sunflower and soybean oils) with and without extractants (di-2-ethylhexylphosphoric acid (D2EHPA) and tributylphosphate ()), were investigated into their potentiality as greener substitutes for the conventional petroleum-based organic solvents to extract Cu(II) from aqueous solutions.
Extraction of copper from aqueous solutions
This technical result is achieved by the fact that in the known method of extraction of copper from aqueous solution, comprising the contact of the extractant and the solution, stirring the mixture, settling and separation of the phases, as the extractant used vegetable oil, and the extraction is carried out at pH 4 and the regulation of pH in
The goal of our work is to demonstrate that the aqueous extended-surfactant-based method is a viable alternative for vegetable oil extraction. In our method, ground oilseeds were dispersed in the aqueous surfactant solution, allowing the oil to be liberated from the seeds as a separate phase from the aqueous phase. The impact of pH, shaking intensity, shaking time and seed
