Fate of uranyl in a quaternary system composed of uranyl, citrate, goethite, and Pseudomonas fluorescens.
This study investigated the partitioning of uranyl within a quaternary system made up of uranyl, citrate, goethite, and the bacterium Pseudomonas fluorescens. In the absence of cells, uranyl was sorbed to goethite as a complex involving surface groups and/or citrate. Measurements of the evolution of CO2 indicated that the addition of bacterial cells lead to the gradual biodegradation of citrate...
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 کاملCesium adsorption on clay minerals: an EXAFS spectroscopic investigation.
Cesium adsorption on the clay minerals vermiculite and montmorillonite is described as a function of surface coverage using extended X-ray adsorption fine structure spectroscopy (EXAFS). Cesium (Cs) possessed a variable coordination environment consisting of Cs-O distances between 3.2 and 4.3 A; however, disorder typical of the Cs coordination environments prevented the resolution of all oxygen...
متن کاملCompetitive Interaction between Phosphate and Citrate on Goethite
Interaction between various species in natural systems may affect the adsorption of these species and thereby their mobility and bioavailability. Recently an ion adsorption model has been developed, based on the surface structure of metal (hydr)oxides and the structure of surface complexes identified by spectroscopy. This model has been applied to the adsorption of phosphate and weak organic ac...

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 ...
