Adsorption of a gold-iodide complex (AuI₂ ⁻) onto cellulose acetate-polyaniline membranes: Equilibrium experiments
The adsorption of AuI₂ ⁻ complex onto acetate cellulose-polyaniline membranes was investigated. Kinetic experiments showed a rapid adsorption of this complex, which was attributed to an ion-exchange mechanism. Equilibrium adsorption results were represented by the Langmuir model, showing a correlati...

| description | The adsorption of AuI₂ ⁻ complex onto acetate cellulose-polyaniline membranes was investigated. Kinetic experiments showed a rapid adsorption of this complex, which was attributed to an ion-exchange mechanism. Equilibrium adsorption results were represented by the Langmuir model, showing a correlation coefficient of 0.9852. Langmuir parameters K and Qm were found to be 0.2937 L mg⁻¹ and 1.2394 mg g⁻¹, respectively. Approximately 94% of AuI₂ ⁻ was adsorbed when a solid/liquid ratio of 40 g L⁻¹ (grams of membrane/ liter of solution) was used. |
