Enhanced As (V) Adsorption Properties in Sn-Substituted Goethites - Changes in Chemical Reactivity and Surface Characteristics
(International Journal of Innovative Research in Engineering & Management, 2015-11)
In this work, the adsorption of arsenic (V) onto crystalline substituted goethites was studied for samples with different Sn- contents. The highest Sn-content of the prepared samples was 5.5 (expressed as 100?[Sn]/[Sn]+[Fe]) ...
Heterogeneous photo-Fenton process mediated by Sn-substituted goethites with altered OH-surface density
(Elsevier Science SA, 2019-08)
Heterogeneous photo-Fenton process using several pure- and Sn-incorporated goethites was investigated for the decolourisation of methyl orange (MO). The used goethites presented a partial Sn(IV)-for-Fe(III)substitution. ...

The chemistry of some Brazilian soils: Element mobility during intense weathering
(Chemical Geology, 1979)
Chemical data for 56 elements in soils from three regions of Brazil (Bahia, Amazon,
Goias) indicate that intense chemical weathering leads to a product soil essentially in the
system, SiO~--AI20 ~ --F%O3--H~O. The major ...
