ABSTRACT. The study aimed to determine the optimal conditions for adsorption and elution of iron from acid mine drainage by ion–exchange resin LEWATIT MonoPlus TP 207 under a batch regime of operation. Langmuir’s sorption equation was employed to analyse the equilibrium data from the experiments. The data fitting demonstrated that the process obeyed pseudo–second–order kinetics with a linear regression coefficient (R2) of 0.9999. Because of the higher demand for hydrochloric solution (100 g/ L) for the ferric iron elution, we studied the effect of the preliminary stage of galvanic elution of Fe(III) to Fe(II) in the presence of H2. In that way, a slightly acidic solution (30 g/ L) was sufficient to desorb more than 95 % of iron from ion exchange resin LEWATIT MonoPlus TP 207 at a temperature of 70 °C.
Keywords: iron, LEWATIT, sorption, reductive elution
