11 p, 371.7 KB Combined effects of tannate and ageing on structural and surface properties of aluminum precipitates / Yu, G. (Chinese Academy of Sciences. Institute of Soil Science) ; Saha, U. K. (University of Saskatchewan. Department of Soil Science) ; Kozak, L. M. (University of Saskatchewan. Department of Soil Science) ; Huang, P. M. (University of Saskatchewan. Department of Soil Science)
The influence of organics on the crystallization of Al precipitates has been well documented. However, the effects of organics and ageing on the transformation and structural configuration of Al precipitates in relation to their surface and charge properties are not fully understood. [...]

(Canadian Light Source) ; Kozak, L. M. (University of Saskatchewan. Department of Soil Science) ; Huang, P. M. (University of Saskatchewan. Department of Soil Science)
The chemistry of Al transformation has been well documented, though little is known about the mechanisms of structural perturbation of Al precipitates by carbonates at a molecular level. The purpose of the present study was to investigate the structural perturbation of Al precipitates formed under the influence of carbonates. [...]

Department of Mineralogy and Geology)
A detailed stratigraphic and facies reconstruction of a bentonitized acid-tuff succession, deposited within the transgressive systems tract of the Upper Miocene-Sarmatian Ser-3 eustatic cycle, at Sajóbábony, northern Hungary, was performed via petrographic, mineralogical and geochemical analyses. [...]

18 p, 1.3 MB Kinetics of citrate-induced selenite desorption from montmorillonite as affected by complexation with hydroxyaluminum and hydroxyaluminosilicate ions / Saha, Uttam Kumar (University of Saskatchewan. Department of Soil Science) ; Kozak, L. M. (University of Saskatchewan. Department of Soil Science) ; Huang, P. M. (University of Saskatchewan. Department of Soil Science)
The citrate-induced desorption kinetics of pre-adsorbed Se from montmorillonite (Mt) and its complexes with hydroxyaluminum (HyA-Mt) and hydroxyaluminosilicate (HAS-Mt) were studied. The mole fraction of pre-adsorbed Se released in 24 h from different clays followed the trends of Mt≫HAS-Mt>HyA-Mt with a significant increase with elevated citrate concentration in the desorbing solution. [...]
