Abstract
ABSTRACT Firstly, original poly(vinyl alcohol-co-ethylene) (PVA-co-PE)/cellulose composite membranes were prepared and characterized. Then these composite membranes were applied for wastewater treatment. For this purpose, separation of Iron (III) and Copper (II) ions from the aqueous solutions with stirred ultrafiltration cell was investigated. These metal ions were complexed by using alginic acid for enhancing the retention. The effects of pH and concentration on per cent retention and flux were investigated. Ultrafiltration of Iron (III) and Copper (II) solutions were done at chosen parameters. It has been found that these composite membranes can be used in ultrafiltration processes up to 45 psi pressure. The maximum retention was found as 77% for 0.75 × 10−4 M Copper (II) solutions at a velocity of 300 rpm, pressure of 45 psi, pH of 4 in the presence of alginic acid by using 5.25% (w/v) (PVA-co-PE)/cellulose composite membranes.
