Abstract
Anthracite-based Purolate standard sorbent is studied before and after sorption of iron, manganese, sulfate, and nitrite ions, by thermal analysis, X-ray photoelectron spectroscopy, scanning electron microscopy, and nitrogen porosimetry. Correlations are established between the thermal decomposition indices, the mass loss in different temperature ranges, and the results of X-ray photoelectron spectroscopy (relative atomic concentrations in the surface layer of samples), scanning electron microscopy (analysis of microphotographs), and nitrogen porosimetry (specific surface values of the samples).
期刊介绍：
The journal publishes scientific developments and applications in the field of coal beneficiation and preparation for coking, coking processes, design of coking ovens and equipment, by-product recovery, automation of technological processes, ecology and economics. It also presents indispensable information on the scientific events devoted to thermal rectification, use of smokeless coal as an energy source, and manufacture of different liquid and solid chemical products.
