Abstract

The geochemical model of ferrous iron oxidation by dissolved oxygen in closed groundwater systems is created and studied using PHREEQCto find the change of groundwater and solid phase composition as well as to define the sensitivity of specified model to certain parameters, pH (from 5 to 9), temperature (from 4 to 20°C), surface complexation constants of Fe 2+ on ferrihydrite and cation exchange capacity (CEC). As results of the simulations it can be concluded that the model is sensitive for changes of pH and temperature values, exchanger concentrations and has a weak reaction on changes of surface complexation constants.
