cupronickel -- Cu-Ni alloy -- alternating current -- titanium electrode -- hydrochloric acid -- electrolysis -- current density -- current efficiency
Аннотация: The electrochemical properties of the cupronickel electrode polarized by an alternating current in an aqueous solution of hydrochloric acid were studied for the first time. The electrochemical dissolution of cupronickel was carried out in a polarization mode with a frequency of 50 Hz in pairs with a titanium electrode. The current efficiency of dissolution of Cu-Ni alloys dependence on the current density at the titanium (20-120 kA/m2) and cupronickel (200-1200 A/m2) electrodes, the concentration of a hydrochloric acid solution (0.5-5.0 M), the electrolysis duration (0.5-1.75 h) and the alternating current effect (50-300 Hz) were considered. It was observed that the current efficiency of the alloy dissolution decreases linearly with increasing current density at the cupronickel electrode, while the current density at the titanium electrode passes through a maximum value at 60 kA/m2.

potentiodynamic polarization curves -- electrochemical behavior -- thallium -- sulfuric acid -- current density
Аннотация: In this work, the kinetics of electrochemical oxidation-reduction of thallium in aqueous solutions of sulfuric acid is studied by potentiometry. To characterize the mechanism of thallium electrooxidation, the following parameters were calculated: the order of the reaction and the effective activation energy of the process. The impact of electrolysis modes: current density, concentration and temperature of the electrolyte on the dimensional charac-teristics of the obtained thallium (I) sulfate was investigated.

Modified sorbents and their application for extraction of metal ions. [Текст] / N. C. Murzakassymova, N. A. Bektenov, M. A. Gavrilenko // News of national academy of sciences of the republic of Kazakhstan. . - 2021. - №1. - P. 75-79

Кл.слова (ненормированные):
coal -- sorbents -- modification -- sorption isotherm -- sorbent capacity -- oleum
Аннотация: The data on accumulated mining waste in the territory of Kazakhstan are presented. Their processing has become very important in our time. The structure of surface-modified carbon materials with a grafted layer is given. New modified carbon sorbents were obtained, oleum was used as a modifying agent. It was revealed that the capacitive characteristics of the modified sorbent are significantly higher than that of the original one, which will make it possible to more efficiently extract the metal ion from wastewater and technogenic formations. Sorption is an effective method of extracting valuable components from wastewater and man-made formations. This method allows you to recover valuable substances with a high degree of wastewater treatment, which can be purified to the maximum permissible concentration of pollutants and then used in technological processes or in recycling water supply systems. Processing involves ores characterized by a low content of valuable components, fine dissemination and similar technological properties of minerals. The existing technologies for the development of minerals make it possible to use only a small part of the valuable mineral mass extracted from the subsoil, and the rest forms waste, which, as it accumulates and is stored, becomes one of the most significant factors of anthropogenic changes in the environment.

Public environmental monitoring of the state of snowpack in norilsk. [Текст] / N. V. Karmanovskaya, O. V. Nosova, A. V. Kaverzin // News of national academy of sciences of the republic of Kazakhstan. . - 2021. - №1. - P. 95-103
ББК 24
Рубрики: chemistry
Кл.слова (ненормированные):
precipitation -- industrial area -- melt water -- chemical characteristics
Аннотация: It is considered that Norilsk ranks second in terms of atmospheric contamination. Industrial enterprises annually emit large amounts of sulphur dioxide, phenols, and heavy metal particles. The city is located within the Far North and is distinguished by the harsh climate of the subarctic type. The snow cover can lie from 244 to 277 days. Snow is a good sorbent; therefore, the snow cover accumulates solid and gaseous pollutants that enter it from the atmosphere with precipitation or are absorbed from it. The purpose of this study was to analyse the snow cover in the Norilsk industrial region and assess the state of atmospheric air in the winter. To achieve this goal, it is necessary to solve the following tasks: conduct a literature review on a given topic; take samples of snow in various industrial districts of Norilsk; study the dependence of the qualitative characteristics of snow on the sampling site; draw conclusions on the quality of snowpack in different areas of the industrial districts of Norilsk. In the course of the study, the following methods were used: organoleptic, visual, methods for determining water transparency, titrimetric analysis, etc. Heavy metal ions and sulphate ions were not detected in the thawed snow, so no industrial gas pollution was noted in the residential area. Most of the particulate contamination was caused by slagging of roads to improve vehicle traction.
