Three fluorinated bipyridine ligands have been designed and synthesized as chelating agents for the extraction of metal ions in supercritical CO 2 (sc-CO 2 ). The ligand solubilities in sc-CO 2 were investigated at different temperatures and pressures, and the measured data have been correlated using a semiempirical model. The calculated results showed satisfactory agreement with the experimental data. Based on these data, metal ion extraction with the three compounds as chelating agents in sc-CO 2 was performed from spiked filter paper, whereby ligand 1 showed the highest extraction efficiency, especially for Ni 2+ and Cu 2+ . The extraction constants, K ex , of the three chelating ligands were seen to increase with increasing extraction efficiency for the same metal ion in the same extraction system.

“…This study applied a semi-flow type apparatus to measure the solid solubilities of three organic compounds. apparatus is similar as that in our previous research [5]. It is consisted of three sections for the supply of supercritical CO 2 , the equilibrium between the solid and the supercritical CO 2 , and the analyses of the experimental results.…”

“…We have measured the solubilities of organic and pharmaceutical components in supercritical carbon dioxide using a semi-flow apparatus [5,6]. In this study, we applied the same apparatus to measure the solid solubilities of three acidic organic compounds, cinnamic acid, phenoxyacetic acid and 4-methoxyphenylacetic acid, in supercritical carbon dioxide.…”

“…The available solubility data (in mole fraction) of compounds (dyes) have been collected from the literatures, which are listed in Table . In order to find the best optimum values of the special parameter of the model ( S 12 ) and the Peng–Robinson EOS (PR‐EOS) interaction parameters ( k ij and l ij ), an objective function (Eqn ) was defined and minimized using a reliable optimization method described in the paper of Asgarpour Khansary and Hallaji Sani .…”

On the basis of the M‐factor theory, A new piece‐wise equation of state has been developed elsewhere for prediction of compressibility factor. On the basis of this model, a novel model for the special case of Tr<1.1 together with a specialized parameter was developed also. Critical modification on the model is proposed and applied in this work as a result of critical assessment of model application in solute solubility prediction in supercritical carbon dioxide. Two relationships were obtained for S12 that must be implemented together with this equation of state. Using this new modified model, the solubility prediction/correlation will be a straightforward calculation. © 2014 Curtin University of Technology and John Wiley & Sons, Ltd.
