Results of a study into the oxidative modification of lignite (brown coal) humic substances of the Tyulgan deposit are presented. The detoxifying effect of the obtained substances on petroleum hydrocarbons is analyzed using a bioassay method. The study indicates a marked increase in the detoxifying capacity of the humic substances associated with their chemical modification. The greatest detoxifying effect on oil-contaminated soils, amounting to 19 and 42% at doses of 0.01 and 0.1 wt%, respectively, is observed for oxidized humic substances. Conversely, the detoxifying effect of unmodified humic substances is significantly lower: 9 and 2 % at doses of 0.01 and 0.1 wt%, respectively. Thus, the viability of using oxidized humic substances as sorbent-detoxifiers during the phytoremediation of oilcontaminated soil is shown.

介绍了 Tyulgan 矿床褐煤（褐煤）腐殖质的氧化改性研究结果。使用生物测定法分析所得物质对石油烃的解毒作用。该研究表明腐殖质的解毒能力与其化学修饰相关联的显着增加。对于氧化腐殖质，观察到对油污染土壤的最大解毒作用，在 0.01 和 0.1 wt% 的剂量下分别达到 19% 和 42%。相反，未改性腐殖质的解毒效果显着降低：在 0.01 和 0.1 重量％的剂量下，分别为 9 和 2 %。因此，显示了在油污染土壤的植物修复过程中使用氧化腐殖质作为吸附剂解毒剂的可行性。
