Removal of Heavy Metals from Wastewater by Electromagnetic Superabsorbent Nanocomposites

Pollution caused by heavy metals is one of the serious concerns in the field of environmental protection and; therefore, researchers from University of Mazandaran, Iran, produced magnetic nanosorbent at laboratorial scale to purify the contaminated waters.

This research deals with the production of biocompatible electromagnetic superabsorbent nanocomposites, and their application in the removal of pollutants, including lead, cadmium and cobalt, from drinking water. The nanosorbent has been produced through a simple and cost effective method, and it has good performance. After the removal of heavy metals, the produced nanosorbent can be separated from the cycle by using a magnetic field and it can be reused.

Magnetic nanocomposites were produced in this research by using (aniline-co-meta-phenylene diamine) copolymer and iron oxide through in-situ co-precipitation method by using ultrasonic waves at nanometric scale. The researchers are carrying out complementary studies so they can use the superabsorbent in the purification of urban and industrial wastewater to obtain drinking water.
