Aliquat-336-impregnated alginate capsule (Aliquat-336-AC) was fabricated using a facile method. Ionic liquid Aliquat-336 was used as a model extractant owing to its good extraction performance toward precious metals (PMs). Aliquat-336-AC was prepared by dropping the mixture solution (Aliquat-336 + Tween 80 + CaCl2) into the alginate solution. CaCl2was used to form Ca-alginate shell, leading to Aliquat-336-AC. Two types of binary metal solutions, Au (III)/Pt (IV) and Au (III)/Pd (II) were used to evaluate metal sorption capacity of Aliquat-336-AC. The maximum Au (III) uptake in Au (III)/Pt (IV) and Au (III)/Pd (II) systems were 61.38 and 82.97 mg/g, respectively. Whereas, the uptakes of Pt (IV) and Pd (II) were almost closed to zero, indicating excellent Au (III) selectivity of Aliquat-336-AC. A comparative study was carried out between liquid/liquid extraction (LLE) using Aliquat-336 and solid/liquid adsorption (SLA) using Aliquat-336-AC for Au (III) selective recovery from Au (III)/Pt (IV) and Au (III)/Pd (II) solutions. The data of selectivity coefficients (αsel) showed that the values of αAu/Ptand αAu/Pdwere 10253.34 and 5817.61 in the SLA system, respectively. These values were much higher than 2033.38 of αAu/Ptand 1879.80 of αAu/Pdin the LLE system. Therefore, Aliquat-336-AC can be used as a selective adsorbent for Au (III).

En este trabajo una recuperación selectiva de Zn (II) y Fe (III) a partir de los medios de comunicación por sulfato de extracción líquido - líquido usando como agente de extracción se hizo el líquido iónico (trihexilo) tetradecylphosphonium bis-(trifluorometilsulfonil) imida (Cyphos IL 109). Se estudiaron varios parámetros, tales como: la naturaleza de la fase acuosa (HCl, H 2 SO 4 y NH 3 / NH 4 ), concentración de extractante, selectividad, y de re-utilización de líquido iónico. Los resultados experimentales mostraron que en medio amoniacal (NH 3 / NH 4 ) el agente de extracción (Cyphos IL 109) tiene una mayor afinidad por Zn (II) que el Fe (III), la obtención de la extracción de 98% a pH = 9,2. Por otra parte, en medio ácido sulfúrico (pH = 1,8), tenemos 96% de Fe (III) de extracción y sólo 4,8% de cinc. Por otra parte, se encontró que el aumento de la concentración de IL Cyphos 109 podríamos obtener mayores porcentajes de extracción de ambos metales de iones. El factor de separación (S Zn / Fe = 110) indica la posibilidad de selectivamente de Zn (II) recuperarse de Fe (III) cuando están en la misma solución, que puede tener una amplia gama de aplicaciones en industrias tales como la galvanoplastia, donde estos metales están presentes a bajas concentraciones y pueden ser recuperados. También se observó que el extractante cargado puede ser reutilizado después de varios lavados con H 2 SO 4 (2,0 mol L -1 ).
