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.

Hydrogen sulfide (H2S) in acid gas reservoirs is an important source of sulfur deposition in rock reservoirs. Studying the adsorption behavior of H2S in calcite slit-like pore is of great significance for predicting the amount of sulfur in natural gas. In this paper, the grand canonical Monte Carlo (GCMC) method is used to investigate the adsorption of H2S in calcite with slit-like pore. Moreover, the effects of different pressures, temperatures and pore sizes on the adsorption characteristics are discussed. The results showed that the adsorption of H2S goes up with the increasing of the pressure and gradually reaches a saturation level. And the adsorption of H2S decreases with the increasing of the temperature. The excess adsorption of H2S first increases and then decreases with the increasing of the pressure. The effect of the size on the excess adsorption capacity changes with the pressure. Meanwhile, the peak of the adsorbate near the surface of the adsorbent shows a nonmonotonic trend with the pressure.

Modified Diatomite

Fe-diatomite was prepared and applied for the sorption of Pb (II) from aqueous solution. The samples before and after modification were characterized by SEM and XRF. The results showed that iron hydroxide compound has been successfully loaded at the diatomite. Lead adsorption characteristics were studied in a batch system with respect to changes in initial concentration of lead, pH of solution, adsorbent dosage and temperature. It showed that the removal rate increased with pH, adsorbent additive amount, the temperature and decreased with the initial concentration.
