Photocatalytic degradation of nonylphenol by immobilized TiO2 in dual layer hollow fibre membranes

TiO2 nanocomposite based polymeric membranes: A review on performance improvement for various applications in chemical engineering processes

“…[145] studied on the photocatalytic degradation of nonylphenol as a toxic component using a dual layer hollow fiber PVDF membrane in which the outer layer was modified by TiO 2 and also a single layer hollow fiber PVDF/TiO 2 membrane as the control sample. After 4h UV irradiation, the dual layer hollow fiber exhibited an 85% nonylphenol removal with the kinetic rate of 0.0092 min -1 while these values for the single layer were 70% and 0.0062 min -1 , respectively.…”

Nanocomposite materials for photocatalytic degradation of pollutants

“…The MPR showed reasonable permeation flux and anti-fouling properties and the TiO 2 leaching from the nanocomposite during membrane permeation was found about 1.0 ppb [120,121,145]. PVDF/TiO 2 dual layer membrane achieved a 85% removal of nonylphenol after 4 h of UVA irradiation in submerged membrane photoreactor with a kinetic rate of 0.0092 min −1 [123].…”

“…The TiO 2 NPs (7.5 wt%) were dispersed in PVDF (15 wt%) by using dimethylacetamide (77.5 wt%) as a common solvent and then, the mixture was extruded using a triple orifice spinneret to form the dual layer hollow fiber membrane. The co-spinning process provides a uniform dispersion of TiO 2 NP photocatalyst inside the membrane outer thin layer that encompasses most of the membrane activities, enhances the contact of the photocatalyst with UV light and hence it improves the membrane photocatalytic performance [123].…”

Preparation and Characterization of Polymeric-Hybrid PES/TiO2 Hollow Fiber Membranes for Potential Applications in Water Treatment

“…Dzinun et al recently achieved remarkable photocatalytic properties, by preparing double layer PVDF/PVDF-TiO 2 hollow fiber membranes [37,38]. In contrast, only a few works investigated the preparation of PES/TiO 2 hollow fibers (Razmjou et al [25], Zhang et al [39]).…”
