Chemists from the University of Silesia are members of teams whose goal is to develop, effective methods of purifying water contaminated with heavy metal ions. Modified graphene oxide is one of the solutions in this area.

It allows the use of a relatively simple and effective method of sorption of heavy metal ions from solutions with a wide range of pH. Purification involves the introduction of a contaminated solution and modified graphene oxide into the reactor. The solution, after sufficiently stirring, is filtered using special filter paper filters.

The technology that has recently obtained patent protection has been developed in cooperation with scientists from the University of Technology and Life Sciences of in Bydgoszcz. Earlier, the patent obtained for a special polyester fabric that captures toxic lead, cadmium, chromium, cobalt, nickel and zinc ions.
