Phosphate adsorption on goethite and Al-rich goethite
Abstract The adsorption of phosphate complexes on pure and Al-rich goethite surfaces was studied by using density functional theory (DFT) and a periodic slab model. Several phosphate complexes are evaluated on these surfaces, which were not studied in other earlier theoretical works.

Phosphate Adsorption from Aqueous Solutions onto Goethite, Bentonite, and Bentonite-Goethite System
The present paper examines the phosphate adsorption from aqueous solutions onto goethite, bentonite, and bentonite-goethite system. The properties of the materials were studied by X-ray diffraction (XRD), attenuated total reflectance (ATR), and NMR ...

Effect of aging time and Al substitution on the morphology of aluminous goethite [PDF]
Goethite and Al-substituted goethite were synthesized from the reaction between ferric nitrate and/or aluminum nitrate and potassium hydroxide. XRF, XRD, TEM with EDS were used to characterize the chemical composition, phase and lattice parameters, and ...

Enhancement in the Oxidative Stability of Commercial Gasoline Fuel by the Goethite Nanoparticles [PDF]
It is well-established that traces of the transition metals strongly accelerate the gasoline oxidation significantly decreasing the gasoline storage time. This paper explores the opposite effect of the goethite nanoparticles on the oxidative stability of

Comparative dissolution of natural goethite samples in HCl and HNO3
The dissolution of goethite samples in mineral acids from to extreme parts of Nigeria (Osogbo and Kaduna) have been investigated. The rate of dissolution was found to be slightly faster in HCl than HNO3.

DESORPTION OF PHOSPHATE FROM GOETHITE [PDF]
Summary The reversibility of the adsorption of phosphate on goethite was measured by diluting suspensions of goethite on which phosphate was adsorbed with large volumes of phosphate‐free solution at the same ionic strength. The effect on the reversibility of various adsorption and desorption conditions was studied, particularly pH ...
