Abstract
The sulfonation of long-flame coal from the Zadubrovsky mine in the Kemerovo region (Kuznetsk Basin) yields sulfocationite with excellent characteristics. The cation exchange capacity of sulfocationite for 0.1 M NaCl solution is 1.0 mg-eq/g (500 mg mol/dm3). Sulfocationite has a glassy gel-like structure. It is characterized by mechanical strength and chemical stability and may be used for deep demineralization of water at thermal power stations and boiler systems. On the basis of 1H and 13C NMR spectroscopy and elemental analysis, an elementary structure in sulfocationite has been proposed, with optimization by the PM7 method using MOPAC 2016 software.
期刊介绍：
