“Until now, there has been no viable method for purifying finished sulphuric acid at all.
“Until now, there has been no viable method for purifying finished sulphuric acid at all. With such a radical reduction in the mercury content, we come well below the current limit values. Such pure high quality sulphuric acid is in high demand in industrial applications and an important step in reducing environmental impact,” says research leader Björn Wickman, Associate Professor at the Department of Physics at Chalmers.
Sulphuric acid is produced either from sulphur from the petroleum industry or as a by-product in the mining industry’s smelters. In the latter case, mercury, which is naturally present in the ore, can end up in the finished products. Also recycled streams in the smelters can contain mercury.
