Adsorption of iron on Dowex Marathon C strong-acid cation exchange resin was studied.
- el">•
The equilibrium behaviour of iron was accurately predicted by Langmuir isotherm.
- el">•
Removal efficiency was above 96% for an initial level range between 0.5 and 5 mg L−1.
- el">•
Pseudo-second order model describes with utmost accuracy the adsorption of iron.
- el">•
Final iron concentration was lower than limits for reuse of the purified effluent.
