- Adsorption of MCPA on goethite and humic acid-coated goethite.
- Anionic pesticides are adsorbed on the mineral oxide fraction of the soil surface but considerably less on the organic fraction, so that the presence of organic matter causes a decrease in the amount ...

- Infrared spectroscopy of goethite dehydroxylation: III. FT-IR microsco...
- Fourier transform infrared microscopy has been used to investigate in situ dehydroxylation of goethite to form hematite. The characterisation was based on the behaviour of hydroxyl units, which were o...

- Synthesis and characterization of goethite and goethite-hematite compo...
- Aging of synthetic goethite at 140 degrees C overnight leads to a composite material in which hematite is detectable by Mössbauer spectroscopy, but X-ray diffraction does not reveal any hematite peak...

- Sulfate Adsorption on Goethite.
- Recent spectroscopic work has suggested that only one surface species of sulfate is dominant on hematite. Sulfate is therefore a very suitable anion to test and develop adsorption models for variable ...

- Multisite Adsorption of Cadmium on Goethite
- Recently a new general ion adsorption model has been developed for ion binding to mineral surfaces (Hiemstra and van Riemsdijk, 1996). The model uses the Pauling concept of charge distribution (CD) an...

- Anomalous Adsorption of Copper(II) on Goethite
- The adsorption of copper(II) onto goethite is qualitatively different from that of other metal-mineral systems. At pH 5.0 the adsorption isotherms are sigmoid rather than hyperbolic, and the correspon...

- Adsorption of Phosphonates onto the Goethite-Water Interface.
- The adsorption of one phosphonate, two hydroxyphosphonates, and five aminophosphonates onto the iron (hydr)oxide goethite (alpha-FeOOH) has been studied as a function of pH. At phosphonate concentrati...
