Inhibition of ferrous iron Fe 2+ to sulfur driven

The effect of Fe 2+ on the performance of sulfur driven autotrophic denitrification SDAD using S 0 as electron donor was evaluated. The experimental results showed that as initial Fe 2+ concentration increased, nitrate NO 3 removal rate significantly decreased.Fe 2+ ion 0.1 mM and 1 Mm inhibited SDAD rate approximately 10% and 50% and resulted in an

Self diffusion of iron and sulfur in ferrous sulfide

By use of radiotracer techniques, the iron self diffusion coefficient in ferrous sulfide single crystals above 620 K was found to be D = D 0δ exp − 81±4 + 84±20 δ /RT where the exponential units are kJ/mole, D 0 is 1.7± 0.1 10−2 and 3.0±0.2 10−2 cm2 sec−1 for diffusion in the a and c directions, respectively, and δ is the deviation from stoichiometry as given in the

All Ferrous Iron–Sulfur Clusters

2012 12 8   Iron–sulfur clusters are important biological cofactors that are used for electron transfer and also for reactivity. Though the iron atoms in these clusters are typically a mixture of ferrous iron II and ferric iron III, there have been reports of biological iron–sulfur clusters in which all the iron atoms are reduced to the iron II oxidation state.

Ferrous iron oxidation by sulfur oxidizing Acidithiobacillus

The ability of elemental sulfur oxidizing A. ferrooxidans to immediately oxidize ferrous iron or pyrite without a lag phase was only observed in bacteria obtained from growing cultures with elemental sulfur. However, these cultures that shifted to ferrous iron oxidation showed a low rate of ferrous iron oxidation while no growth was observed.
