Coated Magnetic Nanoparticles Used to Purify Contaminated Water
Tehran, Iran | Posted on December 28th, 2015The nanosorbent can also be used in various industrial and agricultural sections to eliminate organic and inorganic compounds from polluted water after being mass produced.
Water contamination and obtaining optimum efficiency in purification of drinking water and industrial wastewater are among the most important concerns of human societies at the moment. Although there is high concentration of organic or metal compounds in industrial water, it is even more important to purify microbial pollution in drinking water, specially in distant areas where it is difficult to find drinking water.
The researchers modified and coated the surface of ferrous magnetic nanoparticles to produce a nanosorbent to eliminate organic and inorganic pollutants from water. This research tries to create stability by modifying the surface of nanoparticles, and also to make selective the sorbents by selecting the appropriate coating.
Magnetic nanosorbents are separated very easily after the purification process by using an external magnetic field; therefore, there is no need for an individual separation stage or the application of centrifugal methods to recover the nanosorbent. The separation and recovery processes become simpler, faster and more cost effective this way.
The surface of magnetic nanoparticles were coated and modified by using metalorganic compounds. Then, the product was used to eliminate environmental pollution from industrial and agricultural polluted water.
