Phosphate sorption by minerals having surface Fe-OH or Al-OH groups is an important process in highly weathered tropical soils. In this study, P sorption in 12 samples of soils of a typical hydrosequence of the Cerrado region (Brazil) was predicted by means of combining data on: (1) the amount and properties of gibbsite, goethite, hematite and kaolinite, and (2) the P-sorption characteristics of these minerals, according to existing data in the literature. The concentration, crystal morphology and surface area of these four minerals were studied by X-ray diffraction (XRD), thermogravimetry, transmission electron microscopy (TEM) and N2-adsorption. |
