GOLD 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 ...

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 کاملOuter Sphere Adsorption of Pb(II)EDTA on Goethite*
FTIR and EXAFS spectroscopic measurements were performed on Pb(II)EDTA adsorbed on goethite as functions of pH (4-6), Pb(II)EDTA concentration (0.11 μM 72 μM), and ionic strength (16 μM 0.5M). FTIR measurements show no evidence for carboxylate-Fe(III) bonding or protonation of EDTA at Pb:EDTA = 1:1. Both FTIR and EXAFS measurements suggest that EDTA acts as a hexadentate ligand, with all four o...

Madrid, L. and De Arambarri, P., 1978. Adsorption isotherms and hysteresis of proton adsorption by goethite. Geoderma, 21: 199-208. The adsorption of H+ions by goethite is only partially reversible and the adsorption process is faster than desorption. The adsorptian isotherm shows two inflexion points at pH y,alues 7.5 and 9.5, which can be attributed to the existence of two ar more types of OH...
