The study develops a novel catalytic adsorption material for remediation of soils contaminated by toxic rocket fuel components (RFC). Modified carbon–mineral material (MCMM) sorbent is produced using shungite rock and modified using iron (III) chloride and manganese (IV) oxide. MCMM production process is developed, and MCMM remediation efficiency is tested using soil samples from rocket separating parts impact sites with RFCs contamination. The structure of shungite and the physicochemical parameters of MCMM, the soils contamination at the impact areas of the rocket separating parts, and the ways rocket fuel components transformation in the soil were investigated. The obtained MCMM showed the efficiency of sorption and catalytic decomposition of the rocket fuel transformation products and determined the optimal conditions for remediation. The index of soil detoxification at a concentration of the analyzed decay products is from 0.1 mg/kg to 3.21 mg/kg is from 81.1 to 98.8%.
