Examples of ferrous

ferrous
Ferrous materials and paper recycling, and, to a lesser extent, plastic, are a well-established business in the region.
These probably represent the maximum values since partial re-equilibration between the ferrous and ferric species during separation will yield lower measured fractionations.
At this stage, for each three moles of ferrous iron supplied by olivine, one mole of hydrogen forms.
Ferrous ions detected in iron-overloaded cord blood plasma from preterm and term babies: implications for oxidative stress.
Iron-rich olivines have both reasonably fast reaction rates and contain ferrous iron in a solid-solution between the two olivine end-members fayalite (iron) and forsterite (magnesium).
Moreover, the assumption that the ferrous iron is only oxidized by oxygen is likely to fail when nitrate is present in appreciable amounts.
Ferrous sulphate in a hydrocolloid matrix preparation (gastric delivery system) is associated with fewer side effects because of the slower release of iron ions.
This may lead to a reduced activity of the ferrous iron and less consumption of oxygen by reaction (2).
The first region is characterized by oxygen consumption by the oxidation of ferrous iron without producing hydrogen.
After a sharp transition into a reduced solution, the hydrogen production becomes proportional to the amount of ferrous iron released.
In patients with gastrointestinal disturbances, iron may be given with food or an alternative oral iron medication may be substituted (ferrous fumarate, ferrous gluconate).
Oxidation of released ferrous iron may consume oxygen to such an extent that water decomposes and form molecular hydrogen.
Oxidation of ferrous iron by nitrate might prevent the lowest oxygen levels and thus inhibit hydrogen formation.
Dissolution of pyroxenes that contains ferrous iron will contribute to the hydrogen formation, but to a much less extent than olivine.
Doublets correspond to ferrous present in silicate phases such as olivine and orthopiroxene.
