Hexavalent Chromium Reduction by Ferrous Sulphate Heptahydrate Addition into the Portland Clinker

Abstract Nowadays, hexavalent chromium and its content in Portland cement is very actual and often discussed topic. The goal of this study was to observe the influence of different ways of addition of ferrous sulphate heptahydrate on the reduction of hexavalent chromium at the hydration of Portland clinker.

Study on kinetics of Fe (II) oxidized by air in FeSO

Introduction In hydrometallurgical processing, considerable efforts have been devoted to find alternative routes for leaching metal sulphides. Ferric ion is a well-known oxidant for most sulphides, which has advantages as higher rates can be achieved, elemental sulphur can be generated, and air can be used as a cheap oxidant to generate ferric ion.
