Sulu Ortamdan Co(II) İyonlarının Ultrafiltrasyonla Uzaklaştırılması

Bu araştırmada; Co(II) iyonlarının sulu çözeltilerden komplekssiz olarak ultrafiltrasyonla ayrılmasıaraştırılmıştır. Co(II) iyonlarının komplekssiz ortamda filtrasyonunda; poli(vinil alkol)/selüloz üzerinekaplama [poli(metil metakrilat-ko-etil akrilat)] kompozit membranları kullanılmıştır. pH’ın, çözeltikonsantrasyonunun ve basıncın tutulma ve akıya etkileri çalışılmıştır. Yapılan bu çalışmada; en iyitutulma pH=3’ te, 0,5×10-4 M derişimle Co(II) çözeltisinde, 30 Psi basınçta ve 400 devir/dk karıştırmahızında % 81,4 olarak bulunmuştur.

Removal of Co(II) Ions from Aqueous Solutions by Ultrafiltration

In this study; separation of Co(II) ions from aqueous solutions was investigated for absence of complex by ultrafiltration. Poly[(methyl methacrylate-co-ethyl acrylate)] covered on poly(vinyl alcohol)/cellulose composite membranes were used in the filtration of Co(II) ions for absence of complex. The effects of, pH, concentration of solution and pressure on the retention and flux were studied. In this study; the best retention were found as 81,4 % at pH of 3, concentration of 0,5×10-4 M Co(II), pressure of 30 psi and stirred velocity of 400 rev/min in the presence at alginic acid.
