ตัวอย่าง ferric

• 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.

• After jarosite precipitation, an arid environment must have prevailed, as jarosite becomes unstable and rapidly decomposes to ferric oxyhydroxides in the presence of new liquid water.

• The spectral character of ferric oxide, oxyhydroxide and oxyhydroxysulphate minerals vary depending on their structure and could be formed in layers in mats to the benefit of multiple phototrophic organisms.

• Could millennium money contribute to a new bridge or tunnel instead of being spent on an unnecessary riverside ferric wheel?

• He died from cancer caused by contact with ferric oxide dust.

• It often contains ferric and ferrous salts, sulphates of aluminium, calcium, magnesium and even free sulphuric acid.

• Precipitation methods using ferric sulphate can deal with phosphates, but it is very expensive.

• The uranium was present in the form of ammonium diuranate associated with ferric hydroxide as solids in suspension, and to the extent of 300 ppm by weight.
