Efficient Removal of Uranium, Other Heavy Metals from Water

Uranium(10/Dic/2013)

A new and efficient method for the removal of uranium and other heavy metals from water has been developed at the University of Eastern Finland. Chemec Ltd., a Finnish chemicals industry company, has purchased the rights in the invention and will introduce the method to the commercial markets. Binding metal ions to a solid material, the CH Collector method can be used within the mining industry, and also in the removal of emissions caused by the chemicals and metals processing industries.

Chemec’s CH Collector method is a potential solution to issues relating to the dangers and recovery of uranium, which have been a topic of much debate in Finland lately. Uranium is a mildly radioactive and poisonous heavy metal, which is naturally occurring in some parts of the Finnish bedrock. When mining other metals such as gold, uranium may be present as an impurity in mining waste waters. A complete removal of uranium from solutions is difficult due to the fact that uranium takes different forms depending on the acidity of the solution. The removal of other heavy metal emissions such as lead, mercury, cadmium and zinc from waters is also challenging.
