Dataset of surface reactions for gwb programs Dataset format: jan14 Surface type: HFO Model type: two-layer Surface potential: variable (specify a value in mV to set a constant potential model) Surface capacitance: variable (specify a value in F/m2 to set a constant capacitance model) Thermo dataset: thermo.tdat * * * Reaction dataset for sorption to hydrous ferric oxide. * * Based on data of Dzombak and Morel (1990) * * Dataset "FeOH+.dat" * * This dataset contains the D&M compilation, expanded to include * surface complexation reactions for which binding constants have * only been estimated (see D&M, 1990, Chapter 10, p. 299). * * Dataset FeOH.dat contains the D&M compilation in the strict sense, * not including the estimated values. * * Reference: D.A. Dzombak, D.A. and F.F.M. Morel, 1990, Surface Complexation * Modeling, Hydrous Ferric Oxide. Wiley, New York, 393 p. * * This dataset is formatted for use with the "thermo.tdat" database.
