ABSTRACT
Previous research in this project dealt mainly with soxhlet extraction in general and related work as purification of solvents and extracts, testing several solvents in terms of extraction power to PAH, stability at boiling point and selectivity. Previously used solvents were methanol, dichloro-methane, trichloromethane, tetrachloromethane, cyclohexane, benzene, toluene, all xylenes, mesitylene, tetralin, tetrahydrofuran and acetic acid.
