The pH coefficient (2.6755e+005) and turbidity
(2.5488e+004) from these function reflect the strong
connection between Fe, pH and NTU. Therefore, increased concentrations of iron in water at
high pH, contributes to increased water turbidity.
Hi Ashwani,
if you want to calculate concentrations of different species of Fe in water, you can use USGS free software - PHREEQC. It can considers equilibrium and kinetic reactions related to Fe in water, and also reaction between water and Fe minerals.
