2,4-Hexadienoic and 1-hexanoic acids have been evaluated as extractant for copper(II). The extraction was carried out using benzene and 1-octanol as solvent at 25 °C and aqueous ionic strength of 0.1 mol dm-3(NaClO4). The stoichiometry of the extracted species and their extraction constants were determined by graphical method. The extraction of copper(II) with 2,4-hexadienoic acid has been found to proceed through a mechanism different from that with 1-hexanoic acid. 2,4-Hexadienoic acid has been proved to be similar in the extraction behavior for copper(II) to benzoic acid. While, 1-hexanoic acid as extractant for copper(II) has been demonstrated to resemble decanoic acid. |
