Laboratorial Performance of Nanocomposite Membrane Improved in Water Purification
Tehran, Iran | Posted on July 28th, 2015The membrane is able to separate dye components from a large amount of water. In case this product is produced at large scale, it can be used in various industries, including textile, dye production and foodstuff to purify dye pollutants.
Creating the possibility to purify and recycle water and industrial water is an important step towards the conservation of water reservoirs after the consumption and water shortage crisis. Membrane purification and separation method is known as a very effective and optimum method which has been confirmed by many researchers.
The aim of this research was to produce a polymeric nanocomposite membrane and to modify its performance. The membrane was tested to purify water and separate dye pollutants as one of the most important pollutions in many industries.
The polymeric membrane is made of polyethersulfone nanocomposite and multiwalled carbon nanotubes were used in its structure. Carbon nanotubes have unique properties and they have numerous applications in the production of nanocomposite membranes. However, the heterogeneous distribution of nanoparticles in the structure of the membrane polymer can be considered as an important problem.
The surface of nanoparticles was coated with polystyrene sulfonate as a new approach to improve the homogenous distribution of nanoparticles in polymer. This method significantly affects the distribution of nanoparticles in the membrane polymer and it modifies the structure and the separation performance.
Results of the research have been published in Journal of Hazardous Materials, vol. 298, issue 1, 2015, pp. 111-121.
