olm.general.DebyeHuckel

olm.general.DebyeHuckel(I, z, r, T=25.0)

Calculates activity coefficient, gamma, using the Debye-Huckel equation.

Uses Equation 2.8 in Dreybrodt (1998) (Processes in Karst Systems).

Parameters:

I : float or array

ionic strength (mol/L)

z : float or array

ion charge

r : float or array

ionic radius (angstroms)

T : float or array, optional

temperature in C, defaults to room temp

Returns:

gamma : float or array

activity coefficient
