At first glance they look like tea bags. And they actually are. But they do not serve to make infusions but to decontaminate water contaminated with potentially toxic metals. Inside the bags, there is no leaves or flowers but graphene oxide. This graphene environmental application, developed by researchers from the Department of Mechanical Engineering and CESAM /Department of Chemistry at UA, promises to help to solve the global problem of water contaminated with toxic metals that is daily released on aquatic systems. In fact the most advanced and expensive decontamination processes cannot achieve removal rates as high as those obtained by this infusion.
In addition to the ease of synthesis and low production cost, this system can be applied in locations without specific infrastructures for decontaminating waters.
