Characteristics of Natural Mineral Sorbent for Water Treatment of Drinking Water from Underground Sources

The results of research of sorption characteristics of natural mineral material – marsh ferromanganese ore are presented. Indicators of physical properties and mechanical strength, specific surface area of grains of ore samples were determined. The high efficiency of extraction of manganese and iron ions from underground waters by this natural material without the use of additional reagents is revealed. The kinetics of the sorption process was studied. It is shown that the extraction of manganese and iron ions from water solutions by marsh ferromanganese ore proceeds by a sorption-catalytic mechanism. For each ion, the values of the sorption capacity of the sorbent, the sorption equilibrium constants, and the kinetic parameters of the sorption process are calculated.
