A seeded ambient temperature ferrit process for the treatment of AMD waters: Magnetite formation in the presence and absence of calcium ions under steady state operation

Author: Morgan, B E ; Lahav, O ; Hearne, G ; Loewenthal, R E Date: 2003 An ambient temperature ferrite process has been developed for the removal of iron and non-ferrous metals from AMD waters. The process involves the controlled formation of magnetite (Fe3 O4 ) that has the capacity to substitute divalent and ... Read more
Sulphate measurement in organic-rich solutions: Carbonate fusion pretreatment to remove organic interferences

Author: Ristow, N E ; Sotemann, S W ; Wentzel, M C ; Loewenthal, R E ; Ekama, G A Date: 2005 Sulphate measurement using a barium sulphate turbidimetric method in solutions with high concentrations of organic material is shown to be problematic. The organics give background colour, which introduces a positive error to the measured ... Read more
