The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.4 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.1 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00005 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.07 SJR: 0.198 SNIP: 0.48 CiteScore™:: 1.1 H-Index: 20

ABSTRAKT

By the method of linear sweep voltammetry the coefficients of chromium and iron distribution during electrorefining in chloride and chloride-fluoride melts have been determined. In chloride melts the Fe(II) and Cr(II) complexes are shown to discharge reversibly. In order to determine the distribution coefficients in chloride melts it is sufficient to know the values of potentials of Fe(II) and Cr(II) peaks of discharge and their concentration in the melt. In chloride-fluoride melts the Fe(II) and Cr(II) fluoride complexes discharge irreversibly and for calculating the coefficients of chromium and iron distribution it is necessary to determine not only the thermodynamic parameters but the kinetic parameters as well, i.e. the transfer and diffusion coefficients and standard heterogeneous constants of the rate of charge transfer as well.
It was established that transition from chloride to chloride-fluoride melt does not lead to a considerable change in the value of the distribution coefficient. The formal standard potentials E*Fe(II)/Fe, E*Cr(II)/Cr, though becoming more negative, change by virtually the same values owing to the proximity of the iron and chromium ionic moments resulting in practically the same complexing ability.
