Iranians design filtersto block pollutants, bacteria

February 15, 2014





Iranian researchers at Islamic Azad University, Science and Research Branch, have designed filters covered with carbon and silver nanoparticles, which block pollutants and bacteria carrying communicable diseases.

The results of this study can be used in medical and industrial sectors as well as auto-making, steel, cement, oil, gas and petrochemical industries, ISNA said.

Air pollution in industrial centers and cities is one of the main problems in the world today, which leads to respiratory diseases.

The designed filter was first developed by means of polypropylene fiber. Next, silver nanoparticles used in the filter collide with bacteria and deactivate it. The filter surface bans the growth of bacteria.

Results of the study have been published in the Journal of Industrial Textiles.
