Development of the wastewater treatment technology for the mine 'Ternivska' of the Kryvyi Rih iron ore plant.

Wastewater treatment in mining and mineral processing technology is a topical problem worldwide. The purpose of this study is to substantiate and develop the technology of complex wastewater treatment for the mine 'Ternivska' of the Public Joint Stock Company 'Kryvyi Rih Iron Ore Plant' with the production of highly purified water suitable for secondary use or ecologically safe discharge into surface water bodies. The proposed technology is based on the sequential application of the following stages: preliminary treatment of contaminated mine waters by coagulation and soda-lime softening methods to remove hardness, suspended solids, and colloidal substances; desalination via reverse osmosis; evaporation and crystallization of reverse osmosis concentrate in a vacuum evaporation unit; dehydration of salt sludge in a centrifuge with drying of salt crystals in a dryer.

Optical hydrogen sensing with high-Q guided-mode resonance of AlO/WO/Pd nanostructure.

Nanostructure based on a dielectric grating (AlO), gasochromic oxide (WO) and catalyst (Pd) is proposed as a hydrogen sensor working at the room temperature. In the fabricated structure, the Pd catalyst film was as thin as 1 nm that allowed a significant decrease in the optical absorption. A high-Q guided-mode resonance was observed in a transmission spectrum at normal incidence and was utilized for hydrogen detection.

Evaluating the Response Time of an Optical Gas Sensor Based on Gasochromic Nanostructures.

We propose a method for determining complex dielectric permittivity dynamics in the gasochromic oxides in the course of their interaction with a gas as well as for estimating the diffusion coefficient into a gasochromic oxide layer. The method is based on analysis of a time evolution of reflection spectra measured in the Kretschmann configuration. The method is demonstrated with a hydrogen-sensitive trilayer including an Au plasmonic film, WO gasochromic oxide layer, and Pt catalyst.
