Chalmers team develops method to reduce levels of mercury in sulfuric acid

Green Car Congress

Researchers at Chalmers University of Technology, Sweden, have developed a method that can reduce the levels of mercury in sulfuric acid by more than 90%, even from low levels. According to a report from the United Nations Environment Programme (UNEP), emissions of mercury to the atmosphere increased by an estimated 20% from 2010 to 2015.
