EXPERIMENTAL AND MODELLING STUDIES OF CAESIUM SORPTION ON ILLITE

Poinssot C.; Baeyens B.; Bradbury M.H. (1999)

A natural illite (illite du Puy) was purified and converted to the homo-ionic Na form. The conditioned Na–illite was characterised in terms of its mineralogy, chemical inventory, and surface properties. The structural ...
EXPERIMENTAL MEASUREMENTS AND MODELING OF SORPTION COMPETITION ON MONTMORILLONITE

Bradbury M.H.; Baeyens B. (2005)

The source terms arising from radioactive/toxic metal waste repositories will contain a multitude of dissolved metal species, as do natural systems. The influence of sorption competition on the uptake of safety-relevant ...
MODELLING THE SORPTION OF ZN AND NI ON CA-MONTMORILLONITE - COULOMBIC EFFECTS ON THE ADSORPTION OF TRACE CATIONS ON CLAYS

Bradbury M.H.; Baeyens B. (1999)

In some previous work titration and Ni/Zn sorption edge/isotherm measurements carried out under a wide variety of experimental conditions on purified Na-montmorillonite were modelled in terms of cation exchange and surface ...
NEOFORMATION OF NI PHYLLOSILICATE UPON NI UPTAKE ON MONTMORILLONITE: A KINETICS STUDY BY POWDER AND POLARIZED EXTENDED X-RAY ABSORPTION FINE STRUCTURE SPECTROSCOPY

Dähn R.; Scheidegger A.M.; Baeyens B.; Bradbury M.H.; Manceau A.; Schlegel M.L.; Morales M. (2002)

The aim of this work was to investigate whether neoformed Ni-phyllosilicates can be observed and identified using transmission electron microscopy (TEM) in combination with energy dispersive spectroscopy (EDS). The ...
SORPTION OF EU ON NA- AND CA-MONTMORILLONITES: EXPERIMENTAL INVESTIGATIONS AND MODELLING WITH CATION EXCHANGE AND SURFACE COMPLEXATION

Bradbury M.H.; Baeyens B. (2002)

The 2-site protolysis no electrostatics surface complexation and cation exchange (2SPNE/CE) model used in previous work to model the sorption of Ni and Zn on Na- and Ca-montmorillonites was applied to sorption edges and ...
SORPTION OF EU(III)/CM(III) ON CA-MONTMORILLONITE AND NA-ILLITE. PART 1: BATCH SORPTION AND TIME-RESOLVED LASER FLUORESCENCE SPECTROSCOPY EXPERIMENTS

Rabung Th.; Pierret M.C.; Bauer A.; Geckeis H.; Bradbury M.H.; Baeyens B. (2005)

Sorption of Cm(III) and Eu(III) at trace concentrations onto Ca-montmorillonite (SWy-1) and Na-illite (Illite du Puy) has been studied under anaerobic conditions by batch sorption experiments and time-resolved laser ...
SORPTION OF EU(III)/CM(III) ON CA-MONTMORILLONITE AND NA-ILLITE. PART 2: SURFACE COMPLEXATION MODELLING

Bradbury M.H.; Baeyens B.; Geckeis H.; Rabung T. (2005)

Sorption edges and isotherms for Eu(III) uptake on Ca-montmorillonite and Na-illite in 0.066 mol/L Ca(C1O 4) 2 and 0.1 mol/L NaC1O 4 background electrolytes, respectively, were modelled using a quasi-mechanistic sorption ...
STRUCTURAL EVIDENCE FOR THE SORPTION OF NI(II) ATOMS ON THE EDGES OF MONTMORILLONITE CLAY MINERALS: A POLARIZED X-RAY ABSORPTION FINE STRUCTURE STUDY

Dähn R.; Scheidegger A.M.; Baeyens B.; Bradbury M.H.; Manceau A.; Schlegel M.L.; Chateigner D. (2003)

The nature of surface complexes formed on Ni uptake onto montmorillonite (a dioctahedral smectite) has been investigated over an extended time period by polarized extended X-ray absorption fine structure (P-EXAFS) spectroscopy. ...
