摘要

对来自克麦罗沃地区（库兹涅茨克盆地）扎杜布罗夫斯基煤矿的长焰煤进行磺化处理后，产生了具有优良特性的硫铁矿。在 0.1 M NaCl 溶液中，亚硫酸盐的阳离子交换容量为 1.0 mg-eq/g（500 mg mol/dm3）。亚硫酸根具有玻璃凝胶状结构。它具有机械强度和化学稳定性，可用于热电站和锅炉系统的水深度脱盐。根据 1H 和 13C NMR 光谱以及元素分析，提出了亚硫酸盐的基本结构，并使用 MOPAC 2016 软件通过 PM7 方法对其进行了优化。

Sulfonation of Long-Flame Coal

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.
