Removal of Fe(III) and Cu(II) ions from Aqueous solutions by polymeric composite membranes

In this research, in the new membrane development study; Composite membranes were produced using poly (vinylalcohol - co - ethylene) and cellulose filter. It has beenused in the separation of Fe (III) and Cu (II) ions from aqueous solutions of the produced composite membranes without complex and in the presence of complex agents. It is complexed with alginic acid (AA) in order to keep metal ions well in order to achieve high dissociation. Ultrafiltration trials were carried out using a batch ultrafiltration cell. Pressure, stirringspeed, pH and concentration difference were used as parameters in this study. In the results of the study, using 5.25% (m / w) poly (vinylalcohol -co - ethylene) / cellulose composite membrane in the presence of alginic acid at 300 rpm at a pressure of 45 Psi and at pH 4. It was observed that the highest separation efficiency for 5x10-4 M Fe (III) concentration was 50%. The highest separation efficiency for Cu (II) ions is 5.25% (m / w) at pH 4, 45 Psi pressure, 0.75x10-4 M Cu (II) concentration and 300 rpm speed in the presence of alginic acid. Poly (vinylalcohol -co - ethylene) / cellulose composite membrane efficiency was observed to be 77%.
