0 relating to or containing iron, especially with a valence of 3. -- ซึ่งประกอบด้วยธาตุเหล็ก
These probably represent the maximum values since partial re-equilibration between the ferrous and ferric species during separation will yield lower measured fractionations.
The ferric ion catalyzed decomposition of hydrogen peroxide in perchloric acid solution.
Ferric-ferrous ratio and oxygen fugacity calculations for primary derived melts: calibration of an empirical technique.
Sections were stained with this solution, followed by a wash with 50% alcohol, and finally stained with a small drop of ferric chloride.
The precipitation of magnetite by reaction (3) consumes ferric iron and indirectly drives the oxygen consumption by reaction (2).
Unfortunately these gels suffered from ferric ion diffusion following irradiation, which effectively blurred the dose distributions and limited their usefulness.
The top of the section includes somewhat thicker sandstone beds with syneresis cracks and ferric mineralizations (at 26.6 and 27.9 m).
These anoxigenic photosynthesis reactions probably contributed to the formation of some oxidized ferric iron that may have played a role in early oxygenic photosynthesis and changes in the atmosphere.
