Latest Patents
Dag Berg holds a patent for a method titled "Method for the removal of mercury from sulphuric acid with thiosulphate precipitation." This invention relates to a method for removing mercury from dilute sulphuric acid. According to the method, the sulphuric acid solution is scrubbed with an aqueous solution containing thiosulphate, which precipitates the mercury present in the sulphuric acid solution either as mercury sulphide or, in a chlorine-containing environment, as a mercury sulphide-mercury chloride double salt. The quantity of thiosulphate to be fed is adjusted so that it precipitates the mercury in the sulphuric acid solution, but still does not form elemental sulphur. This innovative method addresses a critical environmental issue by providing a safer way to handle hazardous materials.
