Transport Properties

General transport properties

• Long. disp. (alpha-L): [L] Longitudinal dispersivity.
• Trans. disp. (alpha-T): [L} Transverse dispersivity.
• Coef. mol. diff.: [L²]/[T]. Coefficient of molecular diffusion in the porous medium.
• Decay const.: 1/[T]. Constant for first-order decay.
• Bulk density: [M]/[L³]. Mass of porous medium per bulk volume. (Absent when neither adsorption nor ion exchange is simulated.)

Linear Isotherm (see formula)

• K_d: [L³]/[M]. Equilibrium distribution coefficient

Freundlich Isotherm (see formula)

• K_f: Freundlich adsorption constant
• n: Freundlich exponent

Langmuir Isotherm (see formula)

• K_l: Langmuir adsorption constant: [L³]/[M].
• Q: Maximum number of adsorption sites

Ion Exchange (see formula)

• Km: Ion-exchange selectivity coefficient
• Q^: Ion-exchange capacity
• C0: Total-solution concentration
