Cu(II) İyonlarının Sulu Çözeltilerden Poli(Vinil Pirilidon)-Poli(Vinil Alkol)/Selüloz Membranlarla Ayrılması

Bu çalışmada Cu(II) iyonlarının sulu ortamdan uzaklaştırılması kesikli karıştırıcılı ultrafiltrasyon hücresi ileyapılmıştır. Poli(vinil pirilidon)-poli(vinil alkol)/Selüloz membranları kullanılmıştır. Aljinik asit polimerleritutulmayı arttırma amacıyla kompleks ajan olarak kullanılmıştır. Cu(II)’nin sulu çözeltileri değişik pH, basınç veçözelti konsantrasyonu ile filtre edilmiştir. Cu(II) için en uygun tutulma değeri %2 (m/v) poli(vinil pirilidon)- %2(m/v) poli(vinil alkol)/Selüloz membranları kullanılarak AA varlığında pH 6’ da, 30 psi basınçta, 0.5x10-4 MCu(II) konsantrasyonda ve 400 devir/dakika karıştırma hızında %82.9 olarak bulunmuştur. Bu membran ağırmetallerin sulu çözeltilerden ayrılmasında kullanılabilir.

Removal of Cu(II) Ions from Aqueous Solutions by Poly(Vinyl Pyrrolidone)-Poly(Vinyl Alcohol)/Cellulose Membranes

In this study separation of Cu(II) ions from aqueous medium was investigated by batch stirred ultrafiltration cell. In this study, Poly(vinyl pyrrolidone)-poly(vinyl alcohol)/cellulose membranes were used. Alginic acid was used as complexing agents to enhance the retention. Aqueous solutions of Cu(II) were filtrated at different pH, pressure and concentration of solutions. The optimum retention for Cu(II) was found as 82.9% using 2 (w/v)% poly(vinyl pyrrolidone) - 2 (w/v)% poly(vinyl alcohol)/cellulose membranes when filtration was carried out in the presence of AA at pH 6, pressure of 30 psi, concentration of 0.5x10-4 M Cu(II) solutions and mixing speed of 400 rpm. This membrane can be used to separate heavy metals from aqueous solutions.
