Transitional metal adsorption in variable charge soils have been well studied by several authors [1, 2] but has not been treated for the case of calcined substrates prepared with oxidic
refractory lithological materials.
This condition is probably due to the oxidic
mineralogy and high clay content of the soil, which impart high aggregate stability (Arruda et al., 2010).

and reduced alumina-supported molybdate and heptamolybdate species by in situ laser Raman spectroscopy," The Journal of Physical Chemistry C, vol.
This could take shape in the development of oxidic
catalysts for a novel method to produce ultrapure isobutene or in the continuous further development of a titanium silicalite catalyst for the synthesis of propylene oxide to support the growing demands our customers face with regard to profitability and environmental protection.
The study of perovskites, oxidic
compounds with the chemical formula AB[O.sub.3] and an ideal or distorted cubic crystal structure, is of both academic and technological interest.
These values are compatible with oxidized magnesium in an oxidic
form, like MgO and/or [Mg.sub.2]Si[O.sub.4].
The calcined Au-Fe nanocomposite samples contained both metallic Au and oxidic
Au-Fe interactive species.
No further reduction of oxidic
slag components takes place.
This observation indicated the presence of small superparamagnetic iron oxidic
The soil in this area was identified as Malacca series (clayey-skeletal, oxidic
, isohyperthermic Typic Hapludox).
In order to determine the chemical (oxidic
) composition of the fly ash XRF analysis was carried out, the results are given in Table 1.
