Using Nanoparticles to Remove Micro-Contaminants From Water

There may be a new way to efficiently remove micro-contaminants from water.

Researchers from ETH Zurich have created a new approach to removing chemical substances from water using multiferroic nanoparticles that induce the decomposition of chemical residues in contaminated water.

A variety of chemical substances including cosmetics, medications, contraceptive pills, plant fertilizers and detergents are used daily throughout the world. These everyday items are often difficult to fully remove from wastewater at water treatment plants and ultimately ending up in the environment.

It currently requires an extremely complex process based on ozone, activated carbon or light to remove these critical substances in wastewater treatment plants.

In the new approach, the nanoparticles are not directly involved in the chemical reaction, but rather act as a catalyst to accelerate the conversion of the substances into harmless compounds.
