Abstract
Analysis of the qualitative and quantitative composition of 13 representatives of polycyclic aromatic hydrocarbons (PAH) in the samples of coal from the Pikhtovskiy area of the Kedrovsko-Krokhalevskoye black coal deposit in the Kuznetsk Basin was carried out. Extraction of PAH from coal was performed using organic solvents (hexane, toluene, dichloromethane) in an ultrasonic field; quantitative determination was carried out by means of high performance liquid chromatography. It was demonstrated that the most efficient extracting agents are dichloromethane and toluene. Benzo(a)pyrene was detected in coal samples. Its content varies from 0.004 to 0.042 mg/kg; maximal concentrations were determined for phenanthrene - up to 0.535 mg/kg.
