Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

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%.
