A GLOBAL MODEL FOR THE EARLY DIAGENESIS OF ORGANIC CARBON AND ORGANIC PHOSPHORUS IN MARINE SEDIMENTS Tromp T.K.; Van Cappellen P.; Key R.M. (1995)Sediments are the main repository in the oceanic cycles of carbon (C) and phosphorus (P). In order to relate the deposition of organic C and organic P from the water column, and ultimate burial in sediments, we present a ...

Yifeng W.; Van Cappellen P. (1996)STEADYSED1 is a multicomponent reactive transport code for steady-state early diagenesis which fully incorporates the reaction couplings among the elements, C, O, N, S, Fe, and Mn. The model is tested against extensive ...
-
Steefel C.I.; Van Cappellen P. (1990)A new approach to water-rock interaction is developed which replaces the assumption of partial equilibrium with a complete calculation of the rates at which minerals form and dissolve. The evolution of reaction-flow systems ...

A PLUG FLOW-THROUGH REACTOR FOR STUDYING BIOGEOCHEMICAL REACTIONS IN UNDISTURBED AQUATIC SEDIMENTS Roychoudhury A.N.; Viollier E.; Van Cappellen P. (1998)A slow flow, plug-through reactor was developed for measuring equilibrium and kinetic parameters of biogeochemical reactions on intact sections of sediment cores. The experimental approach was designed to preserve the ...

Martin-Garin A.; Van Cappellen P.; Charlet L. (2003)Uptake of cadmium ions from solution by a natural Mg-containing calcite was investigated in stirred flow-through reactor experiments. Input NaCl solutions were pre-equilibrated with calcite (pH 8.0) or not (pH 6.0), prior ...

Thullner M.; Van Cappellen P.; Regnier P. (2005)The present study investigates the interaction between microbial growth and activity and the redox dynamics in natural porous media. The impact the transport regime has on this interaction is also addressed. Expressions ...

Slomp C.P.; Van Cappellen P. (2004)Nutrient input through submarine groundwater discharge (SGD) rivals river inputs in certain regions and may play a significant role in nutrient cycling and primary productivity in the coastal ocean. In this paper, we review ...

Knowles-Van Cappellen V.L.; Van Cappellen P.; Tiller C.L. (1997)Seeded fluorite crystal growth experiments were performed at three different ionic strengths, using a constant addition method and NaNO3 as background electrolyte. By varying the fluorite seed concentration, growth rates ...
-
Hyacinthe C.; Bonneville S.; Van Cappellen P. (2006)The availability of particulate Fe(III) to iron reducing microbial communities in sediments and soils is generally inferred indirectly by performing chemical extractions. In this study, the bioavailability of mineral-bound ...

Liger E.; Charlet L.; Van Cappellen P. (1999)Colloidal hematite (α-Fe2O3) is used as model solid to investigate the kinetic effect of specific adsorption interactions on the chemical reduction of uranyl (UVIO22+) by ferrous iron. Acid-base titrations and Fe(II) and ...
