Heavy Metal in Your Water?

Wastewater is polluted with organic pollutants and heavy metals that is being discharged into a wide range of environments, leading to an accumulation of non-biodegradable toxic buildup. To combat this problem, efforts are being made to create a method of combining the use of light as a catalyst and using electrical currents to reduce the dissolved metal cations that for in the polluted water. Using sunlight as a catalyst is also explored in this newly emerging study that could one day be used together to simultaneously remove heavy metals and organic pollutants from wastewater so that it may be recycled and reused.
