Residence Time Effects on Arsenate Adsorption/Desorption Mechanisms on Goethite
and anatase, but it does not sorb significantly to pure clay minerals or soil organic matter (Fordham and NorIn order to make sound decisions regarding arsenate contamination rish, 1979, 1983; Jacobs et al., 1970). Arsenate sorption in soil and water environments, it is necessary to have a thorough understanding of the mechanisms of arsenate sorption and desorption on soils and soil components ...
متن کاملGOLD ADSORPTION ON GOETHITE AND HUMIC ACID COATED GOETHITE. Tosiani
Natural organic matter (NOM) in surficial or ground water exists as a variety of molecular sizes and complex mixture of polyfunctional organic compounds. Adsorption of these organic compounds onto inorganic colloids can alter the physicochemical properties of the solid. Although many classical adsorption models have been developed, little consideration has been given to desorption modeling, so ...
متن کاملDesorption of Phosphate from Goethite
The reversíbilíty of the adsorption of phosphate on goethite was measured by dlluting suspensions of goethite on which phosphate was adsorbed with large volumes oí phosphate-frce solution at the same ioníe strength. The effect on the reversibility of various adsorptíon and desorption conditions was studied, particularly pH, temperature, ionic strength and time of reaction. The apparent irrevers...
متن کاملAdsorption, desorption, and surface-promoted hydrolysis of glucose-1-phosphate in aqueous goethite (α-FeOOH) suspensions.
Adsorption, desorption, and precipitation reactions at environmental interfaces govern the fate of phosphorus in terrestrial and aquatic environments. Typically, a substantial part of the total pool of phosphorus consists of organophosphate, and in this study we have focused on the interactions between glucose-1-phosphate (G1P) and goethite (α-FeOOH) particles. The adsorption and surface-promot...
متن کاملKinetics of Selenate and Selenite Adsorption/Desorption at the Goethite/Water Interface
w Kinetics and mechanisms of selenate and selenite adsorption/desorption a t the goethitelwater interface were studied by using pressure-jump (p-jump) relaxation with conductivity detection at 298.15 K. A single relaxation was observed for selenate Se0:adsorption. This relaxation was ascribed to Se0,2on a surface site through electrostatic attraction accompanied simultaneously by a protonation ...
