1.5 L, the power of the UV lamp was 120 W, and the working solution was
continuously recirculated during the irradiation time at a flow rate of 1 L/min.
The photocatalytic membranes titanium dioxide/titanium (TiO 2 /Ti) and cobalt
(Co)-doped TiO 2 /polymer were kindly supplied by B.I.T. s.r.l (Milan, Italy). The
photocatalytic membrane TiO 2 /sisal fiber was prepared by impregnating the support
material, namely, the sisal fiber, in a suspension of TiO 2 –sodium silicate. The
deposition of TiO 2 on the sisal fiber was performed layer upon layer. The sodium
silicate solution was used as binder agent. After impregnation, the obtained
photocatalytic TiO 2 /sisal fiber membrane was exposed to air for 2 days in order to
remove the excess slurry and to dry completely. Finally, the photocatalytic TiO 2 /
sisal fiber membrane was rolled in a cylindrical shape and then washed in distilled
water.
