Abstract:
The extraction of copper(II) with decanoic acid in some alcohol solvents was carried out at 25 °C and at 0.1 mol/dm3 (NaClO4) aqueous ionic strength. Alcohols used are cyclohexanol, 1-pentanol, 1-hexanol, and 1-heptanol. In these solvents, monomeric and dimeric copper(II) decanoates are responsible for the extraction. Species involved in each organic phase are CuA2, Cu2A4, and Cu2A4(HA)2 (HA: decanoic acid). The dimerization and adduct formation of copper(II) decanoates in each organic phase are written as: 2CuA2\oversetKdim−1\ightleftharpoonsCu2A4 Cu2A4+2HA\oversetβad,dim\ightleftharpoonsCu2A4(HA)2 The following dimerization and adduct formation constants were obtained: logKdim−1=2.23 and logβad,dim=0.26 for cyclohexanol, 2.26 and −0.03 for 1-pentanol, 2.77 and −0.04 for 1-hexanol, and 3.04 and −0.24 for 1-heptanol, respectively.
