Dispersion-free extraction of In(III) from HCl solutions using a supported liquid membrane containing the HA324H+Cl− ionic liquid as the carrier
Abstract By reaction of HCl and the tertiary amine HA324, an ionic liquid denoted HA324H+Cl− was generated and used in the transport of indium(III) from HCl solutions. Metal transport experiments were carried out with a supported liquid membrane, and several variables affecting the permeation of ind...

| Résumé: | Abstract By reaction of HCl and the tertiary amine HA324, an ionic liquid denoted HA324H+Cl− was generated and used in the transport of indium(III) from HCl solutions. Metal transport experiments were carried out with a supported liquid membrane, and several variables affecting the permeation of indium(III) across the membrane were tested: stirring speed, metal and acid concentrations in the feed solutions and the carrier concentration in the supported organic solution. The metal transport results were also compared with those obtained using different carriers in the solid support. A model that described indium(III) transport across the membrane was proposed, and the corresponding diffusional parameters were estimated. |
