CHROMATOGRAPHIC SEPARATIONS OF ZINC, IRON, AND COPPER METAL IONS THROUGH CELLULOSE POROUS SOLID FIBER SUPPORTED SOLID MEMBRANE IN MIXED SOLVENT SYSTEMS

Abstract

An interesting aspect of chromatographic separation of zinc, iron, and copper metal ions through a cellulose porous solid fiber supported solid membrane from source solution to receiving phase has been explored in mixed solvent systems. The cellulose porous solid fiber supported solid membrane was prepared by chemically immobilizing tartaric acid. The experimental variables explored were concentration of copper, zinc, and iron metal ions, hydrochloric acid, composition of mixed solvents, and stirring speed. The efficiency of a cellulose porous solid fiber supported solid membrane system has been evaluated for the separation of metal ions. The pre-concentration of metal ions was carried out from the dilute solutions. The two-channel chromatographic cellulose porous solid fiber supported solid membrane system has been investigated for the transport of metal ions from the source solution to receiving phase. The capillary action phenomenon in the cellulose micro fibers plays a significant and active role in the transport of ions through the cellulose porous solid fiber supported solid membrane in mixed solvents.
