Scientists at the Academy of Sciences of China have created a new material that can purify contaminated water by means of light and a material made of networks of graphene and titanium dioxide.
The Chinese team stated that the graphene catches the dirt and the titanium acts as the photocatalyst and accelerates the process of photochemical degradation of toxic organic substances. The new material reduces the concentration of heavy metals, and can be effectively used for the treatment of industrial effluents. The new model was successfully tested in Shanghai and the provinces Jiangsu and Anhui.
According to test results, indicators of water quality in rivers and lakes have increased markedly two weeks after placing networks of the new material. Reports indicate that it the material is already produced on an industrial scale.
