Polyamide/TiO2 nanocomposite membranes applied to the degradation of dyes from textile industry

Conference Dates

September 11-16, 2016


Electrospinning is a technique used to produce high porous fibre membranes with high permeability, small pore size, high specific surface area, good interconnectivity between the pores and suitable mechanical properties.

The application of nanomaterials in membranes allows designing and creating advanced membranes that have been carefully tailored to meet specific requirements

Electrospinning polymer solution containing a nanophotocatalyst can be employed as alternative to immobilize the photocatalyst on nanofiber web, to increase surface area for photocatalytic activity.

Nanofibers of polyamide with different amounts of TiO2 were obtained by electrospun and the photocatalytic activity was measure.

The efficient performance of the photocatalytic nanofibers is mainly achieved by the synergetic combination of a highly porous structure and a high surface area.

The full advantage of the new membranes in water treatment are the lower feed pressure, the higher permeate flux with a drastically reduction in energy consumption and fouling diminution. The membranes are applied in the degradation of textiles wastewaters and the sustainability of the treatment is evaluated.
