The conventional route to producing sulfuric acid is via the contact process. The first step in this process is sulfur combustion which yields 12% SO 2 in air, resulting in larger downstream reactors ...

A bacterium that uses sulfide as an energy source to metabolize solid iron oxides has been discovered, revealing a biological ...

This article describes research to quantify the kinetics of Mn(II) and Fe(II) oxidation by potassium permanganate and chlorine dioxide; illustrates the effects of reduced metal ion concentration, pH, ...
