Reaction mechanism and rate determining step in electrochemical alloy formation for decontamination of mercury from water
Research Project , 2020 – 2022

Mercury in water is a considerable environmental problem that affects the health of tens of millions of people in the world. Also in Sweden, mercury pollution is a serious problem and the mercury content in fish in most of our lakes exceeds the regulated limit. In the industry where mercury is used, as well as for recycling and decontamination, there is a great need for new and better methods for removing mercury from water. In this project, experiments and detailed calculations will allow us to determine the reaction mechanism and the rate limiting step in a new and very promising technique for mercury decontamination. The new method has high efficiency and can capture more than 99% of mercury in an aqueous solution, is selective, has low energy consumption, is reusable and creates a simplified secondary waste handling. By studying the reactions on which the technology is based, the project will enable a large-scale implementation of the technology, which will reduce emissions from industry, provide increased opportunities for sanitation and ensure clean drinking water.
