olm.general.approxI¶
- olm.general.approxI(metals_conc)[source]¶
Calculates approximate ionic strength from the total concentration of metals.
Uses equation 2.19 or 2.20 in Dreybrodt (1988). Approximation is good in most natural karst waters.
- Parameters:
- metals_concfloat or array
concentration of metals (mol/L)
- Returns:
- Ifloat or array
ionic strength
