STRESZCZENIE
In this work, the process of water deironing by using magnetite as a catalyst to accelerate the oxidation of iron ions in an aqueous medium was investigated. It is shown that the efficiency of iron ion extraction depends on the solution concentration, sorbent dose and contact time. In all cases, the use of magnetite accelerated the process of extraction of iron more than an order of magnitude in comparison with similar experiments on the oxidation of iron without the addition of a catalyst. At pH values greater than 6, the use of magnetite as a catalyst contributes to the deep purification of water from iron ions.
