- Abstract
In the present study, the effect of titania sol concentration, hydroxy ethyl cellulose (HEC), and sintering temperature of Titanium ultrafiltration membrane elaboration were evaluated using Box–Behnken and investigated by pores diameter. The titania ultrafiltration membrane has been prepared by the sol gel technique. A deflocculated suspension of titania was obtained by mixing 20 mL of titania sol (0.5–1 mol/L) and 10 g of HEC (2%–5% w/w aqueous solution) as binder. The titania layer was deposited on the inner surface of clay support by slip casting with a contact time (15 min). After drying at room temperature, the TiO2 membrane was sintered (300°C–600°C) for 2 h. The optimal factors to elaborate the TiO2 membrane with pores diameter of 5 nm by using Box–Behnken design include a sintering temperature of 600°C, TiO2 sol concentration of 0.5 mol/L and 2% of HEC. The interaction between the factors were relatively less important.
