Exempel på 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.
