Formation of colloidal particles of hydrous iron oxide by forced hydrolysis
(2000-08-01)
The mechanism of formation and growth of hydrous iron oxide (FeOOH) during the initial stages of forced hydrolyses of ferric chloride aqueous solution was studied by small angle X-ray scattering (SAXS). The effect of the ...
Couraças ferruginosas e solos associados em diferentes ambientes do Quadrilátero Ferrífero, Minas Gerais, Brasil
(Universidade Federal de Minas GeraisBrasilIGC - DEPARTAMENTO DE GEOGRAFIAPrograma de Pós-Graduação em GeografiaUFMG, 2018-07-04)
The litolithic variability, coupled with a complex geomorphological development, makes the region of the Quadrilátero Ferrífero (QF) have a rich diversity of soil cover. Among these, the soils derived from rocks with high ...
