Study of sorption of Fe2+ cations on ferromanganese nodules

Abstract
This work is focused on one of the important problems of many metallurgical industries: wastewater treatment from heavy metals, in particular, from effluents containing soluble forms of iron. Most often for this purpose various imported expensive sorbents with ion-exchange function are used. The purpose of this work was to compare the sorption characteristics of already known and used in filtration processes inorganic sorbents and new mineral raw materials - iron-manganese nodules. The results of the experiment showed that the sorption capacity of nodules can be compared with that of crushed concentrates of pyrolusite. Thus, it is possible to recommend ferromanganese nodules for use instead of already known and used in filtration processes inorganic sorbents for water purification from iron (2+).
