IMMOBILIZATION OF NI BY AL-MODIFIED MONTMORILLONITE: A NOVEL UPTAKE MECHANISM

Nachtegaal M.; Scheidegger A.M.; D?hn R.; Chateigner D.; Furrer G. (2005)

The sorption capacity of montmorillonite clay minerals for small cations, such as Ni2+, can be greatly enhanced by modifying the clay mineral with Al(III). In this study, the mechanisms of Ni uptake by Al-modified ...
KINETICS AND MECHANISM OF LIGAND-PROMOTED DECOMPOSITION OF THE KEGGIN AL13 POLYMER

Amirbahman A.; Gfeller M.; Furrer G. (2000)

The effect of five low molecular weight organic acids (oxalate, malonate, salicylate, phthalate and benzoate) on the decomposition kinetics of the Al13 polymer was studied in acidic aqueous solutions using a flow-through ...
ON THE CHEMISTRY OF THE KEGGIN AL13 POLYMER: KINETICS OF PROTON-PROMOTED DECOMPOSITION - III. A GENERALIZATION ON THE DISSOLUTION RATES OF MINERALS

Furrer G.; Gfeller M.; Wehrli B. (1999)

The decomposition of the polynuclear Keggin Al13 species (Al13O4(OH)24(H2O)127+ or Al13) has been examined as a function of pH (2.06 =< pH =< 3.50), ionic strength (I = 0.1 and 1.0) and temperature (10°C =< T =< 65°C) using ...
STEADY-STATE MODELLING OF BIOGEOCHEMICAL PROCESSES IN COLUMNS WITH AQUIFER MATERIAL - 1. SPECIATION AND MASS BALANCES

Furrer G.; von Gunten U.; Zobrist J. (1996)

A laboratory column containing aquifer sand was used to study biogeochemical processes occurring in groundwater. As a carbon source for the microbially mediated processes, lactate was introduced into the system.To describe ...
STEADY-STATE MODELLING OF BIOGEOCHEMICAL PROCESSES IN COLUMNS WITH AQUIFER MATERIAL: - 2. DYNAMICS OF IRON-SULFUR INTERACTIONS

von Gunten U.; Furrer G. (2000)

Serial data from column experiments were used to develop a dynamic model to describe the evolution of concentration profiles of redox-sensitive chemical components such as iron(II), sulfate/sulfide, FeOOH(s), and FeS(s). ...
