Abstract
The accumulation of highly mineralized waters and
brines in the mining-industrial regions of Ukraine carry a
threat of salt pollution of underground and surface water
sources. Low-waste processing of these waters is prevented by
iron compounds, hydrogen sulfide and sulfur-containing
organic compounds. The process of accumulation of iron
compounds in brines and groundwater in the presence of
hydrogen sulfide has been studied. Comparative calculations of
the thermodynamic potentials of the corresponding reactions
have been carried out. The calculation results are confirmed by
experiments on model solutions and brine of the Dombrovsky
quarry. To remove iron compounds from brines and other
highly mineralized waters, it is proposed to use electrolysis with
inert anodes. It was found that 99.9 % of iron compounds pass
into the precipitate of iron hydroxide (III). At the same time, the
overwhelming amount of heavy metals also passes into the
sediment.
